Yet for all the harm caused by Johnson's War on Poverty and its various welfare programs, a great deal of damage has also been caused by Nixon's War on (Some) Drugs. You wanna talk about fatherless homes? Throwing hundreds of thousands of mostly young men in jail for the "crime" of using, possessing, buying, or selling certain mind-altering substances is a surefire way to wreck families. And enforcing the relevant "laws" in a blatantly discriminatory manner is a surefire way to keep racial tensions simmering.
Let's not forget, either, that the poor are far from the only ones who have become addicted to the state's largesse. Many of the rich also feed at the government trough, in the form of corporate subsidies, protective tariffs, supply management schemes, and other similar rackets championed by one political wing or the other, if not both. That kind of entitlement dependency has also been destigmatized, allowing unproductive cronies to sidestep the need to do gainful work.
The United States, and the industrialized world more generally, does have a cultural problem. It's called Big Government, and it undermines individual character formation by distorting the feedback each of us gets from the world. But it's a problem that partisans on both sides of the political spectrum, in different ways, need to address.
