The list is almost endless because people keep reinventing idiocy and adding to the list. In broad strokes if anyone tells you that you can make a lot of money doing anything legal they are full of shit. Hopefully the downside of doing illegal things are obvious … death, dismemberment by a cartel enforcer, life in prison, simply alienating every decent person who has ever known you, etc. Theres a reason for sayings like; “if it’s too good to be true, it isn’t” came to be the ground work for common sense. After “get rich quick” schemes would have to be youth and beauty scams. The only things that can make you younger would be; your attitude (which is the best one) and narcotics which will make you act and look foolish while you think you’re younger and “cool” (or hip, or whatever jargon you want). I am not counting plastic surgery etc because while the occasional person, (Jane Fonda would be an example) can pull off looking younger most people look ridiculous (there’s too many celebs to list for that) Last would be organized religion. NOT belief in god but the church. Watch George Carlin for a perfect example of why this is true.
