I appreciate housekeeping while I'm on my trip...but that's what I pay for in my hotel bill. I used to tip housekeeping always, but now won't do so unless I receive better then basic service or have left things a little cluttered. I stopped tipping on a regular and automatic basis when I realized how often I would tip, have left the room pretty tidy, but still come back to find: barely made bed (looked like things had just been tossed on), unvacuumed/undusted room, towels not restocked, soaps/shampoos not restocked (yes, happened at WDW as well). Now they're even reporting that more and more hotels don't wash sheets every day. That means less work for housekeeping as well. So basically, it just seemed like more and more, though housekeeping did the bare minimum, if even that, they were certain to pick up that tip. Then it clicked...these people made minimum + wage. It was not my job to supplement their income at this point unless they actually show they're doing their job or more.
I came from a family that struggled. I worked during high school, worked my way through college without any help. I've done those hard jobs, those tiring jobs, and never expected a tip. Course I was also strange in that I also gave it my best effort. That was why I was working my way through school, so I wouldn't have to DO that forever. Some of them may have tragedies in their own life that may make you want to help them, but it's pretty arrogant to assume that someone staying at that hotel is rolling in it and should share the wealth. What if THEIR child is sick and this is a charitable trip they didn't actually pay for? What if they scrimped and saved every dime for 10 years to make this trip, and it will be just as long before they can take another? What if they dealt with layoffs and job reductions, fighting to survive, and this is the first time in years they're finally on their feet enough to take a trip? Everyone has a story, don't assume you know the situation by looking at them.
I tip anyone who does not make minimum wage, or who has to spend their income towards their job: wait staff, cab drivers (some who have to rent their cabs from the company), hair stylists (plenty have to rent their chairs from the salon), valet, pizza delivery (pay for gas/car). Cruise staff...for sure, since they only make about $50/month, they really DO rely on their tips. I tip anyone who I can see is honestly trying to do the best job they can, or who go above and beyond. Then again, these days I'm delighted if a counter person bothers to smile at me. I think I would tip one just for managing to beat me to a "thank you!"
Everyone claims to tip b/c these people are doing ugly jobs they wouldn't like to do....on that note, I would think those poor guys you see doing road construction in 100 degree weather, who do make minimum wage doing hazardous work, now THEY are the ones who deserve to have someone pull over and hand them a tip.
