Dude, Synth is nothing if not lazy as fuck, so he will absolutely not do anything like investing. I have personally told him that he would be better off going to the Philippines or something and living like a king (and maybe meeting a decent chick), but he refuses to do anything that will improve his life, or do anything to prep for the inevitable death of his channel. If I earned high 5 figures dicking around in video games, reacting to videos, yelling at my audience, and pushing out one half assed video a month, if that, then I could absolutely make my life one of comfort, luxury, and fulfilment by doing something similar.
I think he is convinced that he will always be able to suckle off of his mommy in perpetuity if the Youtube thing doesn't work out, or he thinks he will actually be brave enough to an hero even though he openly admitted he only didn't kill himself because there wasn't a gun in the house. I tolerated him being a loser when I thought he was at least an honest loser, but at this point I can't blame people for just hating on him when he's also a hypocrite and a liar on top of being 180 pounds of nutless white meat.
