Same here! I find that when you spend the time to actually inspect this concept of 'chosen behavior', it usually turns out to be much less chosen than it initially seems.
Don't get me wrong, in some ways my opinions on the issue enter the very sensitive topic of genetics. I'm by no means a 'fluffy lefty' who believes education solves everything.
But the mere fact that I need to point that out bothers me. From my perspective, without even getting into genetics and whatnot, the 'chosen behavior' thought in regards to the poor is mostly bullshit. Being poor sucks, and a big part of that is a consequence of the fact that society penalizes poverty. Merit doesn't really enter the equation.
