Why do some men/women really think if they are unemployed, or generically bad, it's the duty of others to marry them?

And I mean this for women too. I've seen too many educated women around who don't want to further or earn their own money, but expect to marry a rich person with house-help. Recently, a family friend came over, and the moment he saw me he commented how he heard I have told my family I'll marry the person of my choice and joked about what about him, who will *he* marry then? I then joked back that I forgot his surname, and because my mom and dad were in the kitchen, and I couldn't kick him out without causing a scene and I had to endure a million stupid questions like, 1. Nowadays women don't stay with in-laws, so a good family man like him doesn't get any girls. 2. He is going to do a business (he's unemployed, graduated from college 4 years ago and has never had a job), and then I'll see, there will be a line of prospective brides. 3. Why do women like me always go for these stupid gora pakoras (really??) we are ruining our culture and heritage, and Indian men shouldn't let their women leave like this. I just asked him why he was telling me this and he shut up, and after my dad came to the room he had tea and went away early. Again, this is just an incident. I'm sick of dealing with men like this, and it's always the ones with a horrible personality who creeps women out, and no average girl goes near. Also, even my conservative grandmother knows that girls should have their own jobs so as to not rely on others, but I've seen a few women too, who are more sexist and patriarchal than men, and who subjugate and make others lives miserable, even though they are educated; they simply don't think it's their job to earn. I go through shit like this every time a relative's function pops up. Next time I'll just ask my parents to come to me.
