should stars spend gigantik amount of money??

stars spend lots of money to get ready to a ceremony or celebration such as academy awards or emmys,at least 30000$ each one,spent on jewelry,hair dressing,make-up,shoes,bags, designer cloth... spending that amount of money for such a short time i think should be directed to much noble causes such as donating to homeless people, poor ones in africa and lots of things.But again i think they worked for this money and they deserve to panper themselves with the money they earned by working so what do u think??????
