Taking the lowly paid out of paying tax and Nics has benefits and disbenefits IMO.

Being slightly left of centre on economic matters and slightly right of centre on social matters, I have mixed views on the matter.
I obviously support progressive taxation, that is, the more one earns not only is more tax paid but it is paid at an increasing rate.
But paying no tax or NICs at all means that the person involved makes NO contribution to paying for services such as defence, education, health-care, the law, probationary services and a host of other things.
Also will it not encourage laziness and lack of ambition?
I know a few women who are well-off but deliberately work P/T in order to avoid paying tax,or who deliberately take low-paid jobs which are below their capabilities.
In other words, they game the system.
