If the wife of a man is frigid, it's not because he can't buy sex that his wife will be less frigid. If his wife is an unbearable bitch, she will still be an unbearable bitch, even if the man buy sex.
And if you knew anything about men's sexuality, you would know that they don't need pornography to masturbate.
Most part of men who buy sex can have sex by others ways.
There has always been two categories of men who have a hard time to have sex: thoses who can wait for a partner without seeking too much and masturbate, and thoses who can't wait without actively seek a partner, but masturbate too. Pornography don't change anything to that.
Capitalism is not a person, it is the produced of spontaneous human action. You're basically saying "people have problem because they have freedom". If people are lonely, it's because they want it, not because of capitalism.I think capitalism is guilty of aiding and abetting this social problem, but ultimately our failure to avoid the pitfalls of our technological progress is the real matter at hand.
