Do you know there was a thriving black middle class in inner city Los Angeles before the manufacturing jobs first started leaving. Not every kid is mentally, emotionally, realistically ready for college. That is especially true in the inner city, or the rural areas.
Right now, with no manufacturing jobs in these areas, you can work at Wal-Mart, or McDonalds for near minimum wage, or deal drugs.
You tell a kid with no father, living in a blighted neighborhood filled with graffiti, chained up houses, that there are no jobs that will allow him to support himself or a family, but he can stay home with mom and work near minimum wage, or he can make more selling drugs in an hour than he can make during two weeks making fries at Burger King, and you get what we have in the inner cities.
We have to have these manufacturing jobs. They are what keeps lower middle class families together. If you tell a young man that his labor is worthless, he treats the system the same way. The fat cat who shipped the manufacturing jobs to Bangladesh in order to pocket a $10,000,000 bonus may think he is safe in his gated community, but for how long?
