What do/did you do for a living?

With the increasingly high priced items people own and are selling, I'm curious about the line of work people do or have done. I thought my $5k integrated was a massive investment, but seeing users searching for $100k speakers or $75k SET amplifiers has me curious about the varying lines of work people do to afford these items. 

Unsuccessful real estate investor, but I am blessed with a supporting wife and a smart kid. i have been in the hobby since early 90s, and went from $2K system to current one which I am very happy with.
