Off the top of my head (and without researching this further) simple things like minimum wage increases have happened, and while it took alot of fighting, that is accomplished by voting.

Minimum wage, the 5-day work week, and other workers gains took decades of violent struggle and organizing by socialists, communists, and anarchists in nearly every country.

My point is that the rulers of a city or town might not be capitalists.

That's not how it works in any capitalist country. Political power is subservient to economic power, and is toothless without it.
