Eh. I think it's insane to spend that amount of money on a wedding, but it's their money. If they want to spend it stupidly then be my guest. Whining about how many people that money can feed is a socialist/communist mindset (ie, funds should be doled out to those who need it, rather than letting some become rich and spend it extravagantly).
Not sure about the "ugly" comments though. Chelsea isn't exactly a supermodel, but she's a moderately attractive girl. I will say that putting up with Hillary as an inlaw would be a bit much though.
Oh well. At least it ends up back into the economy. It's actually far better for the rich to spend their money fast rather than sit on it. If they keep it in the bank then it's just funds removed from the rest of us that sits and rots. When they spend it "we" (the collective economy) get that money back to changing hands again.
