it incentivizes the worker to do well at their job However, tipping only exists in certain jobs, and apparently people who do other jobs do them just fine in the US. So tipping doesn't seem to be necessary. By the way, I also think the tipping issue is a significant annoyance when going to the US. I love visiting the US and definitely it's not a reason for not going (and I don't think the GP meant that either), but probably my most uncomfortable moments there (excluding when I was detained at customs, I think due to having the same name as a criminal) have been when I got disapproving or even downright angry looks for (unintentionally) not giving the expected tip due to not knowing all the details of customs by state, restaurant type, etc.
