I was born in the US to Canadian parents who promptly moved back to Canada where I have lived for the subsequent 55 years. Other than a US birth certificate I had no interaction with the US gov - we politely ignored eachother like a huge number of Canadians in the same situation. The informal status quo was that we both acted as if the "US citizenship by birth in the US" thing had not happened.

Until a few years ago when the US gov declared that I would be a criminal unless I became a full fledged US citizen. They also made this as difficult, expensive, confusing and time consuming as possible. For example having to find some paper documentation that is was living in Canada in 1967 etc. Huge costs - all of it going to specialist accountants - none to the IRS. And a huge complicated ongoing burden.

I am not even allowed to renounce until I have gone through this charade for a few years.

What has the US got out of this? They have processed lots of paperwork on my behalf and they have sent me some (unsolicited) stimulus checks which paid a tiny portion for the (Canadian) accountant fees they have saddled me with.
