I don't know anyone who works more than 40 hours a week, in tech or elsewhere. Those of us in the corporate world have 15-25 days of paid time off (not including holidays, to be clear), based on time with a company. As an employee, I would love to see this increase. As an employer, I would see it as a recruiting opportunity that many job candidates would value.
Most people I know own a home, and others rent houses or apartments at relatively low cost. And probably significantly larger and nicer than European expectations. And they all have plenty to show for their hard work, though much of it may not be enriching our lives substantially.
On the healthcare side, maternity leave is usually only 30 days (not very much, I know, but much better than none). While our healthcare is not "free", I feel like the higher compensation, lower taxes, and lower cost of living in the area enables my family to afford paying higher premiums for better insurance.
Having said that, I still feel anxiety about the future. Losing my job doesn't just mean I lose my income, I also lose my health insurance coverage. I'm not sure how quickly I could switch to an ACA plan with an income-based discount, and I wouldn't be able to afford it otherwise if I had no job.
Unfortunately, I don't think switching to a single payer system alone will address the deep issues in the US healthcare system. People are quick to blame the insurers, but much of the blame also needs to be placed on the providers who charge astronomical fees. The source of the problem, in my opinion, is lack of transparency in pricing resulting from the presence of a middleman (the insurer) and the inability to shop around for many medical services that could be commoditized.
So while I agree that in many ways Europeans have it better (but not without cost in terms of lower wages, higher cost of living, or high unemployment), I don't think painting such a dismal view of the US is warranted. Based on my experiences traveling in Central and South America, a comparison to the third-world, even if limited to work/life balance, is highly inaccurate.
