It does but
1. Things are changing very rapidly. Patriarchy is weaker than it was 20 years ago or even 10 years ago.
2. The situation is much MUCH more complex than feminism makes it out to be. While lower class men are more likely to perpetuate sexism than upper class men, lower class men also have their own issues which leave them unable to benefit from patriarchy. And this isn’t to say upper class men are inherently progressive, because they perpetuate sexism too but are much better at hiding it.
3. Upper class women have the means to cancel out a lot of the negative effects of patriarchy. They can go to private schools, go to university, and have a career which will allow them to put off marriage until they’re ready, and will make them more likely to marry a progressive man.
So basically the only men who benefit from patriarchy are wealthy and/or powerful men, and most Indian men are neither.
