Tipping hotel workers should be illegal

With restaurants, I can at least have sympathy for the fact that the owner can't afford to pay their workers right in the first place. But what is up with hotel workers asking for tips; especially the big named mega corporation hotels. There is NO EXCUSE for why I am expected to tip to have my stuff moved up from the first floor to the nth floor when I am already paying anywhere from 200 to 800 dollars a night.
