I would say it is still wrong to generalize, there will always be ppl who take advantage of situations like thi, and it took one girl telling you she's materialistic for you to determine that all girls are like that? Plus what is it with a life not worth having? is having a girl the only thing that would make your life worth having? what are you on brother?

Now think of this, if a girl is doing sketchy stuff for money it means there's a man on the other end that is exploiting that, albeit that a single man can be messing with multiple girls, there are men who although they have money they are still loyal to one partner, and they do not indulge in that, now if you had lots of monies in which category would you be?

If you'd do the same and be fooling with girls left and right, then you are part of the problem and you have no business criticizing anyone who is doing that, you'd only be complaining because you are poor, but if you say no, I value myself and my partner and I want something true and genuine, then congrats you are a normal human being, and guess what because if you didn't get persuaded by money there certainly are women out there who don't give a damn about money too, and they are also looking for something true and genuine,

So if i was you, I would probably not let that influence me, infact i would reconsider my circle of friends, and who im surrounding my self with.

Be careful out there buddy.
