Democrats have long since realized that people who are poor and dependent on the government will vote for them, even if it is their liberal policies that created the poverty and dependency. That's why every ghetto in America is controlled lock, stock, and barrel by liberal Democrats. Unfortunately, so many destitute Americans have yet to realize that liberal policies don't fight poverty; they maintain it.
Perhaps the worst thing about that is the betrayal of the poor people involved. Most of them are just having a hard time and looking for a little help to make life easier for themselves and their families. Little do they realize that the "help" the liberals are offering is akin to a drug dealer offering them a free sample. Not every liberal intends to "hook" the people they're "helping" on poverty, but they're certainly not very upset when it happens. The more poor dependent Americans there are, the more votes liberals get; the more needed they feel, the larger the budget becomes for the non-functional, big government programs they support.
Liberals have a lot of perverse incentives to keep as many Americans poor as possible and they respond to those incentives in a big way.
1) Overuse Of Welfare Programs: Americans are a generous people and most of us are fine with having a safety net that helps people who get down on their luck. The problem with liberals is that they do everything humanly possible to turn that safety net into a hammock. They oppose limiting the amount of time people can be on the programs along with drug testing and work requirements. Obviously, encouraging people to get comfortable on the dole is bad for the country, but it's even worse for the people involved. It's one thing to get in a tough spot, take assistance for a few months, and then get back on your feet. But, spending years or even decades on the dole? It's a trap that will make you dependent on the government while utterly ruining you as a human being. There was a time when even the staunchest liberals agreed with this sentiment. Conservatives disagree with Franklin D. Roosevelt on a lot of things, but he was absolutely right when he said,
The lessons of history, confirmed by the evidence immediately before me, show conclusively that continued dependence upon relief induces a spiritual disintegration fundamentally destructive to the national fiber. To dole our relief in this way is to administer a narcotic, a subtle destroyer of the human spirit. It is inimical to the dictates of a sound policy. It is in violation of the traditions of America. Work must be found for able-bodied but destitute workers.
