I seem to recall reading (on this forum) that the set of “folks who pay zero income tax” is >30% and < 40% of the population. Many of these are essentially the “takers”. I further seem to recall that 0bama’s “tax plans” would increase that set to somewhere in the neighbourhood of 45% of the population. As long as the folks in that set can vote (essentially, can decide how to spend other peoples’ money), socialism is inevitable.
