If you are minimum wage security guard, nobody is taking your shit.

People with guns accustomed to taking things "out of fairness" or some such... What happens when they run out of rich people to rob, do you think they just stop there? Day one is the rich, day 1000 the dude with a civic and a mobile home on 1/4 acre is looking tempting... Particularly now that almost all the people who knew how to both own and manage businesses have fled and anything that depreciates quickly is running out of parts and consumables.

Better to be robbed by the rich than by the poor? If you're convinced the world is out to get you, what difference does it make?

Do you think it's unreasonable to think people are out to get you as a capitalist in an anti capitalist revolution?

What incentive would this guard have to keep working?

So are you arguing we _should_ make rich people poor so they have motivation to work; that only poor people can be motivated to work?

There won't be any incentive to produce even basic grain stocks if the large majority of the population can't afford to eat. See the Great Depression.

Life expectancy rose to a multi decade (all time at that time?) record peak during the great depression in US and starvation was exceedingly rare. Even at one of its worst the outcome was remarkably robust against starvation.

The solution is simple: Don't be that rich. If you can manage that, then you'll be fine. You're probably not a temporarily embarrassed millionaire.
