(A) Birds of prey (Not free)
(B) Birds of scavenger (Freegans)
Both birds can survive!
But, Uncle8888 rather be Bird of prey.
Investing Camp (C) : Earn more, Save more and Invest for growth-dividends or capital gains!
Investing Camp (D) :
Earn more (Seldom mention), Save harder and harder and then invest for income!
Most commercially vested writers/bloggers are likely to advocate (D) as it is within our control to tighten ourselves more and save more; but to earn more that is not within our control and too difficult to set earning targets. Saving targets are easier to achieve as there more ways to save money.
Who are likely to be in Camp C or D?
You can observe this investing behavior in the personal investment blogosphere.
