Only, a decent chunk of people won't do this, because they cant. Just like they can't function without plastic.
So those peeps make their beds. The prudent ones will be protected.
I run the plastic like crazy, they give out tons of free shit, cashback, points, bonus money for the first 500, 1000 whever you spend. I credit card hop those bitches, get a new one every few months take the free shit, dumb ass's. I always pay em off every month, never balance transfer... and peeps wonder why the banks are going broke.. The next one on my list is a capital one free $100 with the first $500 spent, 1.5% cashback. I'll take that 20% thanks.. The one I been using for the last few months.. free $200 for the first $1000 spent.. 1% cashback, 5% on select stuff, chase freedom.. I could just pay cash, but why?? when I get a 15-20% dicsount to use the plastic..
But do you see the problem? If "those peeps" account for the mass of the economy they don't just make their own beds... It affects the whole economy... It affects you.
Ah but in a pre '33 style system their isn't constant inflation and easy money, easy credit.. Peeps won't get a zillion chances at easy credit, you screw up paying somebody back, you just won't get any credit anymore. The users (aka "those peeps") won't affect shit, cause they won't have any credit or paper or clanking coins, they will actually have to work for a living and live within their means. Peeps from the great depression era are savers, not users.
