Who is paying for your wedding?

I know traditionally it's the bride's parents who are supposed to pay for the entire wedding. But seriously, who can afford to do that these days? My FH and I are looking at places and coming up with ideas with the thought that we would be paying for it ourselves so that we can stay on budget. My mom and step-dad said they would help us, but that they are not going to go broke paying for it. My FH says that he doesn't think his parents would help at all because they feel it is the bride's parents duty. Am I wrong to be pissed off about this? They have also passed comments that my parents should throw us an engagement party - obviously they are very traditional in their beliefs.
A little background on FH's parents - they recently bought a HUGE house in North Carolina, also own a town house in NC where their other son is living while he goes to school, they bought him a BRAND NEW car, and still have a house here on LI that has yet to sell. It doesn't seem to me that they're short on cash if they can do all those things.
So I'm just wondering how everyone else is paying for their wedding. I feel that in this day and age, the cost should be split between the bride and groom, and BOTH sets of parents.
