labor camps. or you can just take them out back and put them out of their misery. in my experience, there are two types of homeless people, people that want to be homeless and people who have no choice but to be homeless. the latter are the ones causing all the problems in society, while the former are hustlers and are tolerated because of their capacity to contribute to the economy. you cannot cure the mentally ill homeless, because that would require forcing them into programs, which the government is averse to doing. hence, the most realistic solution is to round them up and execute them. it is merciful for them, and beneficial to society as a whole. it's not the "moral" choice, but it is the most effective one. there are plenty examples in contemporary america to demonstrate the consequences of leaving these people to own devices.
