Ideally, I'd like to see a society/country where everyone has enough self-respect and self-esteem to want to fulfill their potetial in life. If that were to occur, I think you'd see the poverty stricken all but disappear and the ranks of the upper middle class would swell accordingly. I believe this effort / reward system can only exist in a laissez-faire capitalist environment.
1. let's limit it to a real world discussion and shelve the idealism
Here, let's throw special needs people into the melting pot:
Some things you are born with--autism, mental illness, physical handicap. Some things occur later in life--disease, mental illness, physical handicap due to accident, crime/terrorist victim, war veteran. (With respect to war veterans, any accomodation, e.g., transit, building access, toilet, etc.. has to accomodate all citizens.)
Let's say a man is not part of the current economic problem. He can pay is mortgage, he doesn't have car payments or credit card debt, and he can support his family of 2, soon to be 3, comfortably. Now, let's say his 3rd child is autistic. In your Darwinian world, he's not fit to survive.
Look, brah, this is hurting your brain because republicans have the luxury of exclusion. And make no mistake, YOU would
"Free markets" (figment of your imagination) don't take care of by-products of capitalism, hence federal agencies like the EPA exist.
And who in your imaginary "free market" world will "police" white collar criminals? Any policing agent (government), securities or neighborhoods, enforce laws created by congress (government) and upheld by the judicial system (government).
The longer you remain silent, the longer this list will grow and the more mental suffering you'll be subjected to.
