Re. healthcare, from past people I've hired and let go and friends who've been unemployed, perhaps as they're all in tech with higher incomes, it seems pretty accurate. I remember one employee had to setup Cobra to continue keeping their healthcare plan, and it was actually more expensive than what the company was paying for some reason! Terrible system in general...
Re. 401(k), I understand these are privately managed accounts, but the rules around them are dictated by the government, and can be changed as many countries are doing in general. And there are penalties for withdrawing before 59.5years, which I would call the "retirement age" on these plans. I completely get the math of deferring taxes on your investments, and employer contributions, but I prefer to find other tax strategies that lock in tax savings today and also have more freedom around what we do with our money, these plans are pretty restrictive and I suspect will only get more restrictive in future as I mention in the blog.
With regards to my paranoia, I did link to a full blog on Privacy explaining that position, but specifically this attempt which fortunately failed: https://abcnews.go.com/Politics/biden-admin-backs-tracking-b...
I could be wrong, but this is one of many examples I've heard about since moving here, the general theme being they want more powers to get our data and audit us. Since moving here, our experience is the IRS is way more aggressive and invasive with tax filings and penalties than we ever experienced in the UK too. And don't even get me started on the exit tax, which for some reason kicks in after 8 years if you're on a green card, requires you to list every asset you have worldwide, and then pay capital gains on it, if you ever decide to leave the USA one day!
