Nothing wrong with it, and outside America is means so much more when you do it because it is genuinely voluntary rather than "customary".
But since you are asking questions, I'll throw one back at you...
The Hell is wrong with paying your waiters and waitresses a decent living wage to begin with?
I'd be all for an increase in a service industry minimum wage and removing the exemption for restaurants and the like to pay below minimum wage, but unfortunately my countrymen have yet to see the wisdom in giving me full control of our government.
That said, I've known many waitresses/waiters/bartenders/etc. and almost to a man/woman they make absurdly more money for a 20 hr. a week job than the average joe working their 20 hr. a week part time deal. A lows are real low, but when the highs are coming home after a 4 hour shift with $200 cash in your pocket I don't think the $3/hr. wage is of biggest concern.
Also, while it's customary it still means just as much to waitstaff when someone goes above the 15% range in most places (20% in major metro areas). In fact, I'm a big fan of the sliding scale effect it can have, as in non-tipping countries I have no solid recourse to passively show dissatisfaction since any tip is viewed as a "plus". In the U.S. all waitstaff start out at a 20% baseline for me and can work up or down the ladder. If you do a shit job you'll notice when I give a 0-10% tip. If you're great you'll get 50% or better.
LOL, nice work being correct on facts and still being a bit silly.
What's so silly about it? Size and climate variance plays a big role in just how strong a nation's natural attractions will be. Australia is a beautiful country with amazing parks and refuges, but does it have anything similar to the Tongas National Forest or Glacier National Park? Of course not, there isn't an alpine/sub-arctic climate regime on the continent. The size and breadth of the United States were ideally paired with it's history of early ecological preservation to produce the largest, most varied natural conservation program in the world. It ties directly into the massive natural resources advantage the U.S. has thanks to it's geographical orientation.
way to shit on the majourity of your workforce.
Guess they need more bootstraps.
You misunderstand my point. Do I feel that it's right to put quality healthcare behind an achievement wall when passage through that wall is increasingly less about merit and more about which side of the wall your parents where on? Not in the least. I'd be all for universal single payer healthcare.
But the reality is that if you have a good job and therefore employer subsidized healthcare along with enough disposable cash to have a flex account, meet co-pays, etc. then the United States offers by far the best healthcare you can get. Elite medical professionals, designer drugs, etc. etc..
A lot of work needs to be done to expand that quality of care to the entirety of the nation instead of restricting it to the top ~50%, but it doesn't change the fact that on an individual level moderate success begets a wealth of rewards in the U.S..
That's really the United States in a nutshell. If you can make it into the top 50% economically life is pretty awesome. If you happen to be a white male not only is it easier to make it into that top 50%, but it's even better when you get there.
