My biggest problem with the so-called "War on Poverty" is that it seems more intended to keep bureaucrats employed and grievance-mongers busy than to actually alleviate poverty. For proof, just consider the quantity of money wasted every year (emphasis mine).
Since its beginning, U.S. taxpayers have spent $22 trillion on Johnson's War on Poverty (in constant 2012 dollars). Adjusting for inflation, that's three times more than was spent on all military wars since the American Revolution.The federal government currently runs more than 80 means-tested welfare programs. These programs provide cash, food, housing and medical care to low-income Americans. Federal and state spending on these programs last year was $943 billion. (These figures do not include Social Security, Medicare, or Unemployment Insurance.)
Over 100 million people, about one third of the U.S. population, received aid from at least one welfare program at an average cost of $9,000 per recipient in 2013. If converted into cash, current means-tested spending is five times the amount needed to eliminate all poverty in the U.S.
We could "solve" poverty for one-fifth the current price if we eliminated all our means-tested programs (and all the bureaucrats who run them) and simply wrote checks to the families below the poverty line. It seems like this kind of money-saving, welfare-enhancing program is just the kind of thing that could win support from a majority of Americans.
As for structure, my preference would be one or more negative income tax brackets that reward people for working.
