The real problem is the tendency to excuse an individual's inability to earn an income as being a problem outside of the individual's control that can (or should) be corrected by others.
Another incredulous stare.
Are you suggesting, as I think you are, that each of these two scenarios differ only in factors INSIDE the control of the individual?FIRST SCENARIO
a) Child born of poor parents, in poor neighborhood, access to lesser quality schools, surrounded by peers who are into rap music, smoking weed, less high school achievement, lack of university education, less income
b) Child born of wealthy parents, in a neighborhood of high fences, pools, tennis courts, access to elite private schools, surrounded by peers who come from like minded families who value education, peer competitiveness at school - on the bus, in study groups, after school, higher high school achievement, access to ivy league university education, MORE INCOME. SECOND SCENARIO
a) Child born inherits genes for -90 IQ
b) Child born inherits genes for +130 IQ
Intervene to change the situation - for a single hypothetical child (imagine this could be done, do a 'thought experiment') - from a) in either scenario to b), and you would raise that child's income, holding other factors constant. In other words the move from a) to b), all else being equal, CAUSES income level.
The point: Well, since whether a) and b) pertains isn't (for the most part) under the child's control, and since whether a) or b) pertains causes income level for some particular individual child, the income level that some particular person ends up earning is in large part not under their control!
This isn't to jettison personal responsibility. This is to suggest that it's pretty fucking obvious that personal responsibility operates within certain strong limits
It's also to suggest that the causal factors are significant on a population level. Some individual born in sub human conditions might be wired such that he rises up and becomes the president. But on a statistical/population level, your chances of earning a high wage if you are born in, say, Africa, are greatly reduced than if you are born in Oxford; through no fault of your own (unless, that is, you hold people responsible for where they are born, which is absurd!).
So, if you want to 'kill to poor', then in many many instances you will be holding people responsible for elements outside their control, which is a strange sense of justice, in my opinion. (Then again, maybe you just don't value justice - which is as it is, but in this case we will simply be talking past each other).
