IDK. When you have (capitalism) willingly charge substantially higher costs on medications like insulin (for a month, it can be anywhere from 100+ dollars to far more (700))
Or a EpiPen, which the average cost is a whopping 700 bucks if your not insured (while in those crazy socialist countries who have removed a for profit healthcare system. Is a mezely 100 bucks for two)
Oh let's not forget the people dying to the exposed elements. Or the people starving. Or people dying to perfectly treatable illnesses.
And that's exluding factors like a for profit military system.
And this is excluding the type of government (authoritarian, or anarchistic)
Meanwhile communism, presuming that it's not a dictatorship (say idk. A direct democracy. So in other words anarcho communism)
You know what the deaths would be?
As little as possible. Because communists don't care about what's in your wallet. We care about other people's well being. There's no point forcing someone into a 40+ hour work grind, if their mental health is in shambles.
(hell that ignores the fact that we don't need the 40 hour work week at all. anything beyond 4 hours and our productivity has proven to tank.)
Hell conventional jobs would just be phased out, doing the same kind of work over and over day in and out is not healthy. It leads to burn out.
And it's not like no work would be done, someone still has to manage the sewers, someone still has to keep track of the electric grid. doctors are still needed.
But instead of some private business's manager handling shit. The community would handle it, aka, the people that fucking live there. Instead of relying on some private company who's just looking for the next set of massive profits.
Tl;dr Captalism has a fuck ton of blood on it's hands. From the Military, down to the United States horrible For profit healthcare system, which profits off of people's misfortunes, and kills through it's paywall. Anarcho communism is a more ethical way (or less radical views such as democratic socalism) would still be far better than Capitalism.
