I'm quite good at apologizing, because I need to do it so often. I get lots of practice.
The American abhorrence for admitting fault and/or apologizing is quite mystifying to me. It's really corrosive.
I've spent 40 years, promptly admitting mistakes, and repairing, where possible.
WFM. YMMV.
I don't accept this premise. Americans don't have a lot of the cultural baggage that leads to this. If anything, Americans are quick to admit fault and address root causes. We don't have a cultural history of beating around the bush, saving face, deferring to elders who are clearly wrong, etc. Individual exceptions abound, but I think on the whole Americans are ready to admit fault most of the time.
Mistake 0 is assuming there's an "American abhorrence" or a tendency held by "Americans on the whole". It's difficult for any American, much less anyone outside of America, to have interacted with each of its distinct, and often wildly divergent, subcultures to find a genuine common thread.
It's also something emotional. I grew up overseas, so I guess it never happened for me, so I sort of stand to the side, bemused.
Even at the individual level you'll see advice like "never talk to the cops" because it could possibly be used against you in the future.

This happens even in work environments where it's unlikely your coworkers will sue you. I feel like perhaps it's more about competitiveness - I've seen plenty of times people raised in US use any kind of admission of mistake as a bludgeon to get advantage, get more political capital or belittle someone elses project. I guess it's considered to be a good thing to grasp any advantage over others?
