An alternative to a meltdown is what's been happening since 2008- the poor start killing themselves and maybe they vote for the wrong guy, but the trend doesn't stop. Given that the market says 30% of the workers don't really matter (and remember, that's people participating in the labor market, which is at a historic low IIRC), maybe they just ignored. They can cause some level of social unrest, but the rich are mobile, and the factories are pretty automated. What we'll see soon is more private security and automated security.
