Yet half of your economy seems to be built around it (tipping).

Bollocks. Tipping is predictable and normative. You assume 15% when going to restaurants, and roughly the same amount in other contexts, like getting a haircut.

No one is fleecing you, and the costs are predictable using basic math.

You may be thinking of Lobbying, which is a totally different phenomenon.

The validity (or lack thereof) of tipping may be debatable, but it's not equivalent to bribery.
