This doesn't really match up to what I see, which is the people who find fascism attractive also idolizing and politically supporting the wealthy. Usually the people admittedly wanting to "rock the boat" are talking about social politics, which leaves little room for sympathy when the tool used is fascism. It speaks of hatred and nihilism, not desperation and inequality.

Inequality can be the root cause, but it is a hard problem to solve. Let alone powerful people who control the media would never want it to be solved. The result is people are not ready to face it directly. Instead they pick an easier solution such as fascism/racism, hoping the solution works somehow. Example: how many people blame foreigners for the absurd housing market? Because it's easier to blame someone else than thinking critically and find the root cause.

Additionally, it makes them more susceptible for the "someone to blame" agenda that these groups use. If your life is great and you have excess, this falls on deaf ears. This also leads towards terrorism and other violence as the futility of this life creates cracks for indoctrination.
