So could Greece borrow more......No.
There has to be a reestablishment of an equilibrium.
Greece, where no one pays tax or at least lower tax than their government spending dictated, used to have inflation, running at 10% or more.
If the government couldn't borrow, except at high rates, it had to print the money to pay government workers, especially as they didn't get enough tax in.
But Greece wanted to join the Euro - cheap borrowings, brilliant, cook the books, get in under the conditions required for joining the Euro, but the constraints mean that borrowings have to be repaid in a hard currency, not the soft inflationary one they had.
So, the fantasy Greek economy, based on the Greek government printing money and inflation was forced into an economic habitat of a hard currency to which it was not adapted.
The Chinese won't lend, the Germans won't lend without conditions that mean that they are not pouring money into a bottomless pit - German money going to other rich nations, e.g. Chinese via Greece, unless the Germans had invested their money in the Chinese companies (bought shares), but then they would be getting income and profit from their own money.
Let me give you an extreme example. Would you spend your life savings on a drug addict, so they can buy drugs where the money goes to drug barons, giving them all your wealth, so you have nothing?
They don't raise enough tax, fast tax rises push economies into recession, so the government has to cut spending. The Greek government cannot print money as it used to, and the Germans won't print money - hyper-inflation and all those problems.
Government cutting spending means recession, especially if the economy was based around government spending.
The problem is that the Greek government, in joining the Euro, has actually caused the problem because they didn't understand the immediate severe economic constraints that were going to be imposed.
Those constraints have to be imposed for the other countries not to be dragged down. If there is political union, and agreement that all European citizens are equal, equal conditions, equal safety nets, equal financial responsibilities, equal financial behaviour, then it works.
But if one country doesn't want the same conditions as the others, it all falls apart.
For the Euro to work, governments have to have the same tax raising ability and powers, and taxes must be equal, social benefits must also be equal, otherwise the different countries, with their different cultures of tax avoidance, benefit rates, etc etc, must have separate currencies, and if the countries cannot borrow the money, or raise taxes, to support its liabilities (costs such as unemployment) the country has to print money, and have its currency inflating, and causing price rises.
AND if one country has a higher unemployment rate, all the other countries have to agree to supporting that, at a rate of expenditure that means that the unemployed can survive, else it all falls apart.
If you want a stable currency, or stable country, you have to have stable tax receipts, and those tax receipts (or hand-outs from other governments) have to pay for the debt of the country, and they have to be stable relative to the debt.
Effectively Greek inflation has been replaced by a deficit (borrowings) that it cannot afford.
And until the tax system gets sorted out, and all Greek assets slowly get repriced, based on the real productivity of the Greek economy relative to the other Euro economies, of course there is going to be hardship. It was bound to happen.
If the Greek government actually restructured their economy slowly over two decades, this suffering could have been avoided, but the attraction of cheap money, was far too appealing, and so they decided to take a short-cut, straight into severe recession.
So there you have it.
A government with its institutions must either, raise taxes, borrow, or have inflation.
You cannot borrow if you do not raise taxes, what creditor would lend money to a government that is only printing money?
And borrowings cause inflation, because you have to pay interest on the borrowings, unless you can grow the economy.
Governments pretend that they can do something about the wealth of a nation, but that wealth is created by companies and products, things other than the essentials of food, water, sanitation, housing.
If a government (the people of a country) creates a product or service and sells it, that gives a bargaining tool for trade, commerce, investment, etc.
What would Keynes do?
I think that there are too many people who have lost sight of basic economics.
The larger the proportion of the population that has to be supported by the tax payers, who are creating the wealth, the tax payers will start to question why and for what or whose benefit they are working, but may forget that their wealth is built on other people being poorer than them. The question is what level of disparity will people stomach?
The Greek papers now show the Germans as Nazis, which was inevitable, they believe that the Germans are unreasonable. But the Germans are not acting unreasonably, it was because of the decision that the Greek politicians made to join the Euro which set off a series of events and economic constraints that were inevitable.
Those inevitable constraints have put an economic pressure on the Greek economy that means it will have to adapt to working within the contraints that a hard currency inflicts on an economy.
The Greek population have to accept the economic discipline that comes with hard currencies, where inflation is stamped out, else leave the Euro.
They could try to change the Euro, and have inflation, but the Germans wouldn't tolerate it, so they might as well have their old currency back if that was their desire.
All economies are like an organism, an energetic system, that in competing with each other have to work efficiently, that have to ensure that income exceeds expenditure.
If expenditure exceeds income the economy declines, the standard of living declines.
This applies to whole economies as it does individuals/companies etc.
The economy might decline back to just farming, or if society breaks down, hunter-gathering, tribal conflicts, the same things that happened in the development of the human race, but those earlier stages would happen again.
If the Greeks created many solar power stations and exported that energy, giving energy that was cheaper than oil or gas, they could earn income from that.
Every civilised country has a welfare bill to pay, either by countries, companies or individuals, someone has to pay, unless someone does it for free, but only the rich can afford to do things for free!
