Well, this year I suppose it will be $1,583.33. That's just the gift tax exclusion ($19k this year) at work. I don't really see a problem with it. People should be able to give money to family members without penalty.
> End tips and raise wages, and the taxes cease to be confusing or controversial.
Some businesses have tried this, but often it doesn't work out. To make this financially feasible, it would require action at the federal and state levels to 1) eliminate different tipped vs. regular tax rates (some places have done this already), 2) and modify how payroll taxes work to even things out a bit. It sounds like "oh, no problem we'll just raise prices by 20% to cover the extra salaries". But no, that doesn't work, because businesses and individuals are responsible for payroll tax on non-tipped salaries.
And there's a collective action problem at play: take two identical restaurants. One follows the now-standard model of accepting tips, and ~20% is customary. Their identical competitor won't accept tips, pays their staff better, and charges 20% more for their food. Fun outcome: people get sticker shock at the second place and go to the first place instead, even though in the end they pay exactly the same amount. Human psychology is dumb, and restaurants know this, so they won't do this unless all their competitors are also required to do it. (This is also why in the US prices are advertised tax-excluded; pricing that includes tax is viewed as more expensive, even if the final charge is the same.)
