> who they cannot coerce

If the market is a consumer need then yeah, these companies can coerce simply by being the only (or one of a few) options in town. Food, healthcare, and housing are all markets that appear to be narrowing which means increasing in their coercive abilities.

It's true that the USSR and East Germany were worse, but that had a lot more to do with the concentration of power into a strongman leader rather than the people. And, in fact, a major part of why West germany did so well wasn't really due to market forces, but rather due to the US spending ungodly amounts of money on rebuilding them (and Japan). The USSR was always pretty cash strapped. Especially since the only nations they could really interact with were nations under the USSR umbrella. Even other communist nations like China had pretty tense and often not friendly relations with the USSR.

In today's money, we dumped about $120B on West Germany. Just to put things in context.
