A "millionaire with three houses" who, for the first fifty or so years of his life, lived on the most meager wages.
Sanders only became wealthy enough to own a decent home when he finally got to the Senate.
In fact, when he first was elected to Congress in 1991, his 89 thousand dollar a year salary caught him priced out of most Washington DC real estate. I know, I grew up there.
Bloomberg's wisecrack reminds me of folks who sneer at rock stars who finally make some good money, because they forget that rich rock star lived on ramen and hot dogs for the first twenty years of their career, or wealthy authors who hit it big, like Chuck Bukowski who never managed to hang onto a place to live for more than two months at a time until he was suddenly "discovered" at nearly age sixty.
And oh, by the way, a lot of legislators in Mike "Manchurian" Bloomberg's REAL party (the GOP) pretend to live frugal lives by "hot bunking" at
"family fellowship" crash pads, not revealing that powerful lobbyists are paying the bill for them.
So not only was it a cheap shot, when it comes from a billionaire all it proves is that Bloomberg is an IDIOT for believing that democratic socialism doesn't want anyone to be wealthy. Nonsense...but ghastly excess is ghastly excess.
There were plenty of filthy rich people walking around in the New Deal era.
There are plenty of filthy rich people in Denmark, Sweden, France, Norway, Finland, Germany, etc.
Basically Mike Bloomberg tried using a Trump tactic which only works with Trump voters.
