If I had a dollar for every American I've seen working at the same companies that was spending $800+ a month for healthcare insurance coverage for themselves, their spouse, their two kids... And then over the course of a year probably a few-thousand in "co-pays" for doctors visits and minor things where the insurance doesn't pay 100% of the doctor visits. And then they still would have a $8,000+ deductible for many categories of expensive medical costs per year, if they ever have to use it, before full coverage kicks in.
I am fortunate enough that my spouse has her own very good medical coverage and we do not have kids, so our monthly outlays are somewhat less.
If you consider that $800 to be equivalent to a tax, the person's take home net income was actually less than if they were an equivalent-of-a-W2 employee in Canada or another place with a social healthcare system.
