Healthcare is not free. I pay 250€/month here in Germany, and I literally cannot even access it at all. I go to the doctor and get turned away. They have this shitty two tiered system where unless you have the private insurance or are a pensioner, you have to fight against a thousand bureaucratic dragons to get any service out of it.
University is not free either. I paid 500€/semester and had to source my own food and accommodation. And although I got a degree, you cannot really compare, even the top of the top of German universities with places like MIT or Stanford where you get so much prestige and networking opportunities. One has to compare apples to apples.
I am for both universal healthcare and education, but Americans need to understand that you aren't going to get the American service for the European price point.
This is becoming a fruitless discussion without getting into the specifics.
Here's the thing, with my talent and experience, I could easily be earning 4x as much as I do here in Germany. I work in AI, it's super hot right now. But here in Germany the only job for me is in the public sector, where I get paid like a lowly government employee. It's completely ridiculous when compared to what my fellows in the US are earning. I earn around $45,000 of which I net $25,000 after taxes, of which $12,000 I pay in rent per year. And my benefits? A fixed two year contract. It's not even a permanent position.
I have colleagues who decided to pay out of pocket some $120k to do an MSc. in California so they could access the tech network there and secure a job, and all of them are financially better off than I am.
