In the 1930's John Rockefeller became the richest man in the world with "only" a net worth of about $200 million IIRC. A billi then would probably be closer to a trillion in todays money.There were just a handful....I'm guessing you could count them on two hands...but billionaires by circumstance aren't around those epidemics like that...which usually spread in squalor and crowded areas.
Would it be impossible to get? NO, just highly unlikely considering your environment....you'd mostly be around other uptight rich types who haven't been exposed to that stuff either.
And I still wouldn't take it
