I agree it all comes back to capitalism.

Currently I work at a hospital where we are understaffed to save every last penny. The overworked workers look for someone to take their unhappiness out on. Instead of targeting capitalism, they target each other.

The orderlies complain that the nurses are lazy. People in Materials think the orderlies are lazy, etc, etc, etc. Of course, the orderlies also complain about each other. Everyone back-stabs (in other words, everyone competes) as the worst performers periodically lose their jobs, and so the threat of starvation etc. always looms.
