At $150k/yr, your marginal tax rate is close to 40%, but your overall tax rate is more like 31%. I'm in Saskatchewan, and every time I've played with different income levels, taking into account the exchange rate, we end up paying very similar amounts of all-in income tax, with ours including (most) health care. (Comparing with California)
Once you consider the typical US co-payments to actually use health care, it's cheaper in Canada. Getting an MRI in California cost me close to $1K out of pocket, despite fancy insurance that paid most of it. In Canada it's pre-paid in taxes.
Also when you consider that we don't have to pay anything for insurance to cover that. The MRI costs $0 out of pocket, covered by the healthcare that is already factored into our equal-cost taxes.
There's still a benefit to having health insurance for covering stuff not covered by the gov't plan: vision, dental, some fraction of prescription drugs, etc. I do have a health plan through work, but I think it costs somewhere around $50-75/month to cover all of that stuff for my family.
>They already do! It's called revenue.
I give you a job. I pay you $500. You generate $100 of revenue.
I'm pretty sure I just lost $400, you gained less than $400 after taxes, and the IRS gets to enjoy the spread.
Edit: changed to reflect that there are more winners than just the IRS
