Why doesn't the Roman Catholic Church let married men become priests?

It's really simple. Marriage is an economic relationship. Priests and monks were and are to be devoted to Christ. Disciples are supposed to give up this world and follow Jesus. Allowing priests to marry would open the door to priests marrying into rich and powerful families. The Catholic church decided this was a violation of the calling of a priest. It's really more about money, than about sex. You all always see everything as some hatred of sex and women.
