That's the difference between a corrupt and non-corrupt system rather than a capitalist vs socialist one. Nearly all European countries have an at least somewhat socialist healthcare system but in most you don't have to resort to those tactics.

Humans have tendency to become corrupt

the market / capitalism won’t correct itself, much people want to call it God/ perfect

Regulation, anti-trust laws try to correct somethings but many politicians are against those things because they limit the profit that can be made, profit first, that’s the corruption
