[Harry Potter] Why did Wizards retreat into secrecy, instead of using their powers to become a permanent elite caste ruling over the Muggles?

I think that, despite their magics, they are vastly outnumbered and to rule they would have had to brutally and totally subjugate the muggles. 
Being out in the open and not being in power would leave them open to superstitious muggles conducting witch trials.
