Either side of the spectre lies enshittification:
- more competition comes with margin squeezing and cheapest source for service or goods
- less competition brings the monopoly, the dream of any capitalist (owner, not user).
Either way comes enshittification, and there's no middle balance, it drifts towards one of the sides always.
During the Soviet Union years, tourists to it knew that the thing to do was pack blue jeans in their luggage, which were highly desirable under communism. Wearing blue jeans in the USSR was a mark of status.
we still had luxury goods without monopolies, so I think I'll take more competition please.
This German supermarket system has strong compettion , low margins but it is cheap and reliably good quality what most German wish.
So I disagree.
