The fact really is in the USA if we eliminated tipping, the cost of the food on the menu would just go up by $X number of dollars, and people don't want that, they want low prices for the items on the menu which is why the system also is the way it is.

Looked it up. You were right. Well, at least in the pay structure. 85% of surveyed people prefer a tipping pay structure to including it in the price of food.
I think it has to do with the perceived idea that tipping leaves the diner in control and leaves the ability to punish a bad waiter. Maybe I'm wrong about that too.

I'm sorry doctor that appendectomy scar is a bit to big for my liking I'm only tipping you $180.
After doing this for enough years, it becomes a background task that you don't even really think of, no awkwardness.
It is absolutely insane to me that you would tip anything at all in that case. US tipping culture is crazy.
In what situation would you give 0% tip?
What people have to understand, is that a "Tip" in the United States for a server == Salary, not some nice additional money. It's how they pay their rent/buy their groceries/feed their children.
And, while that "$7.25/hour" is OK in some place like Terre Haute, Indiana, It's destitute poverty in a lot of cities, so the societally agreed convention is that in order to live/pay groceries/utilities/bus-fare/etc... tips are essential.
It's reasonable to assume that when a serving person in the United Stated doesn't receive a tip of 18-20%, then that money is resulting in a reduction of expected baseline salary.
