That's just ridiculous. Inner city kids don't lack the proper incentives to succeed (they're poor, after all), they lack the resources needed to succeed.
I grew up poor in the south. People don't need to be handed incentives to succeed. Some people don't mind being poor. Some people will be poor before long even if you give them a million dollars. If success is important to you, you work for it. Success is defined differently for all of us. Lifelong welfare is not helping someone, it is not incentivizing them. That has to some from within.
I think he meant to say that trust fund kids lack motivation while inner city kids lack the skills.
