I personally think it's idiotic to spend that kind of money on clothes; don't care how good they look.
If I were a millionaire, I seriously doubt that I'd ever spend even half that much on a car. I probably would get something a little nicer than my '97 S-10, but nowhere near a $75,000 vehicle.
Point is there are some things I WOULD spend a $150,000 on, but you probably wouldn't; and as long as I'm spending MY money, and you're spending YOUR money, what difference does it make????
And if I should give you $150,000 with no strings attached, IE no preconditions or limitations, then why should I try to tell you, even then, how to spend it??
Now if I put conditions on the gift, you have the option of following the requirements, OR refusing the gift.
So, why does it make any difference if the RNC spends $150,000 or $5,000 on Palin's clothes. If you have given to the RNC, and did not put any conditions on the gift, they are free to spend it anyway they see fit as long as it is generally in line with the implied/understood purpose of the gift - which is to campaign for the R party.
As for Michelle, I would never spend that kind of money for an afternoon snack- or even dinner, but that's just me. It's her money, and AFAIC she can spend it anyway her little heart desires.
Now when her husband is wanting to spend MY money, we're talking a whole 'nother ball game!!!! But that's another topic
