This doesn't mean that being broke is an advantage. Quite the reverse: it happens because being broke is a disadvantage, so people who succeed despite broke-ness have to have been better in some other respects. (In some cases they might just have been luckier.)
I bet you'll find that professional basketball players who are short are especially fast, that professional academics who score worse on standard intelligence tests are more creative, that expensive houses that are in nasty areas are particularly large or beautiful, that successful singers with unimpressive voices are especially gifted musically, etc., etc., etc. None of this means that those features are advantages.
Sorry, but this is just stupid.
