^This. The first few years I lived abroad I had a company sponsored tax accountant file for me. I was being paid in dollars, living in another country, ok I figured it was complex because of that. Now i have a local job and tried to file my taxes myself. Nothing fancy, no day trading or self employment. Just a middling tech job. When I tried to fill teh forms based on the older returrns, while I could follow what numbers went into which forms, figuring out which forms I would need was non trivial. I could not find any level of assurance that I was complying w/ the relevant statutes. So, back to 500$+ for a tax attorney. Even my 'simplified' returns are 80 pages. I call bullshit or non compliance on anybody who says this is easy.
tl;dr, US citizenship = 500$/year tax.
I did get my children US citizenship. The world will be a very uncertain place in the coming years. The US may get its shit together or it may not but I certainly see a subset of outcomes for this planet where hiding in the country w/ big guns will be advantageous.
