Ok, I'll take a crack at it. You reference the British pub system in which servers make a somewhat livable wage and basically don't get tipped. Valid. Consider the differences in prices there and here, and the fact that you have no option of NOT tipping there, but you have that option here, you get a more merit-based system for the most part. I mean, you've BEEN to Britain, right? See, British servers get the same pay for every drink, not varied by customer. Which is why they have fewer reasons to care about you. Hey, don't feel bad about that part. I can sympathize with some parts of your argument. Welcome to McDonald's, have you tried our McRib?
Here in the states, the servers earn very small 'base' and rely on 'tips'. Really good bartenders and servers have the very realistic option of capitalizing on skill and soon out-compete the low-earners, thus leaving the best candidates to earn the top dollar. This is, in shorthand, the basic system of Capitalism. Are you a Commie, a Socialist? Why do you hate America? If you are a poor tipper, you pay for it yourself rather than pass the cost along to the rest of the decent members of society.
As far as advice, since your argument involves deadbeats (bartenders) earning an unfair pay (or a fair pay unfairly levied? you're unclear on that one) - I'd recommend either getting a job as a bartender (exploit that system to your advantage, unless you're already earning more or can't hack it) or opening a bar that pays a fair wage and doesn't accept tips, and making a killing. Fight the power, ya know.
Or, you could explain what you do and how much you make and why you deserve to earn what you do. What if one can hire someone else for the same amount of work for a fraction of the pay? Why not stay at home and drink at liquor store prices, you can save a BUNDLE! And those damned parking meters downtown! Piggly-Wiggly has no such devices, you common thieves!
<thanx to massimo and white_rabbit for basically predicting what I was going to say, since you both wound up saying most of it better anyhow.>
