The fact that some of us own land and others the rest of us have to pay them to live on it.
Or the fact that we have to pay to have a roof over our heads. Like how is that not essential to living? Why are there people making money out of essential things like housing, schools, electricity, water, etc?
[Edit]
Whoops, I did not intend this to be a comment to you.
But also the marketization and commodification of everything.
Basic necessities like housing and food that there's more than enough for everyone made or being made, being denied to people to keep the price of those commodities artificially high, is not normal. Food being destroyed with bleach and housing being kept empty while people go hungry and sleep under interstate overpasses is not normal.
