Capitalism produces scarcity artificially where there is none.
There is enough food (in fact there’s currently massive amounts of “overproduced” grain being left to rot)
Even without changing the horribly designed production systems, there is no real shortage. People don’t starve, have no fresh water, have no houses to live in, etc. because there are not enough of these things. People don’t have access because capitalism denies them it.
There’s enough to share for everyone. It’s not a zero sum game for poor and oppressed peoples.
