If we're going to go off of what's cheaper, converting homeless people into fertilizer seems best.
There are no social benefits to forcing productive members of society to quietly tolerate and provide for unproductive members. It fosters resentment and tension.
You see, 'social' includes everyone, not just those we re-allocate someone else's resources towards. There's this stupid idea that if someone's a 'victim', they deserve special treatment. No, that's not an axiom. It is only an axiom if you're stupid and haven't gone out of your way to ever really try and 'help' 'victims' - those that have, quickly realize what a bottomless pit it often is.
