The Left doesn’t grasp that Cloward-Piven is a double-edged sword. If conservatives KEEP THEIR ARMS AND AMMUNITION, and sign on to every benefit plan they can while continuing to vote against them, and deliberately reduce income to underfund Mordor on the Potomac, they can hasten what is probably an inevitable collapse and be in a position to dictate terms of any rebuilding (or just flat-out eject or even exterminate the leftists).
C-P produces chaos, which no sane person wants. Only those on the Left think it will work to their benefit.
You are right that once chaos comes, it’s best to be prepared, though. One never knows how it will turn out, and of course I’d hope for it to work out for the good guys. But there will be a heavy price to pay, either way.
