Only the rich may prosper in scenarios of radical regime changes. They simply translate money into power, security, education or mobility. Everyone else has to step down and to suffer more or less.
Aside, fascism and capitalism aren't congruent. There is more to fascism than just economic exploit and vice versa, etc. This is why I said you mixed up categories. Or maybe you are just overgeneralizing.
Finally, transformations into Socialism have to happen globally (Marx said, I believe). That's due to the "constant siege and thread" radicals get; why things turn out bad. You just can't come up with completely new rules within a game of 280 more players.

No translation of money into power maybe in the case of GDR. But a lot into mobility.
