Yes. Wealthy people have more options of escape, means of retaliation. They can actually afford a lawyer and to go to trial. They can hire people to get black mail material or just pay people off.
This isnt to say that opression or discrimination can't happen.
After all no matter how wealthy you are, you still cant enter the exlusive golf club that caters to only rich white men, if you are say black or a woman. And this can make it difficult to further accumalate wealth as alot of deals go down in these places.
And while money does give you the option to say quit a job, if your trying to be the first female surgeon, and the only person willing to mentod you legitamatly is also abusive.
Well you stay.
Cause theirs something worth staying for. (Or the consequence of leaving is to large. After all theirs always a bigger fish)
Wealth can solve alot of your problems, and give you alot of options. Gives you more power to say no and walk away with minimal consequences or an ability to deal with said conseaquences.
But it is only one part of a complex ever evolving system. And theirs alot of reasons why despite being wealthy one can experince discrimination or opression. Often not as bad as a poor person. But poverty is only one version of opression/discrimnation. Sexual orientation, gender, race, age, mental health, disabilites are a few others and they all interplag with eachother.
