I'm not getting into this with you, but kicking your kid out assfirst at 18 is not healthy or responsible. I mean, aside from the fact that you don't know this guy or even know if he lives at home (and the fact that we're all assuming it's a dude, but we don't even know that much), nothing depicted here is enough to assume that OP is coddled, and staying at home until there's a need to move out is not coddling anyway. It's economical, and they do it in most countries around the world. America is pretty unique in that regard, and has only been that way for about 70 years or so, plus the housing market hasn't been stable enough since probably the 80s or before (whenever the bubble burst.)

It seems to me you're just spitting out right wing talking points, and I really do hope that your phrasing doesn't mean you have children. If you do, I seriously implore you to do some research. As for me, I'm done here. You're clearly not going to say anything nice.
