It's not a problem for hotel owners, because they can currently hire housekeeping staff at low wages. It could become a problem for the society, if we raise the minimum wage too high and then the market (people making individually rational choices) makes the situation worse for everyone. The real problem is that we as a society have tied a person's value as a human being to their wealth and income. We have collectively decided that if someone has no wealth and no marketable skills, they do not deserve a good life, no matter how hard they try. Many people want to change this, for everyone at the same time.
