Get Rich Quick

My partner is driving me crazy - he’s like comical character out of an 80’s sitcom with his get rich quick plans.
He goes on and on about making money, telling me about how this person got rich just doing this or that person invented that. It’s got beyond funny and I’m at the point where I just want to yell at him to “shut the F Up”. I’m not a money focused person, I don’t have a lot, I don’t resent anyone that does. I work in hospitality on minimum wage and LOVE it.
He on the other hand has a great job with a fantastic company. He gets a good salary (above national average) and has potential to earn much more BUT he does nothing but whinge bitch waste time and complain that he’s just a minion making money for others. Too be honest I don’t know how he hasn’t got the sack.
His mental health is poor and has suspected ASD.
I don’t seem to be able to get it through to him that being self employed is not a good option for him NOR is it going to bring him this sudden wealth. He’s changed careers many times and it’s always the same. His measure of success is completely money focus. It’s becoming a breaking point for me.
