I tend to agree that if you want income then generally the best way is to buy (sensible) growth and sell shares for the income; but not always. I think it applies when world growth is positive and markets are bullish (isn't that most of the time??) but not otherwise. In bear markets, income stocks are fairly defensive. In the current developed markets, where the tide of share prices is high and 'growth' may be a little stretched, it seems to me that a better play now is to buy income while interest rates seem at last to be on a downwards path. (That is what I and wife have been doing since February, as I've posted here several times). I expect 'growth' from them in proportion. At its simplest, if central bank interest rates were, say, 5.5% and over the next two years decline to 3.5%, then a solid dividend-producing share priced at 100p where the divi was and remains 5.5p should increase in price to around 157p. That is, other things being equal, which of course they never are.
I hope that's right.
