Huh? I've never had a to pay a dollar in healthcare premiums at any employer. Granted, I've never worked for a tiny, tiny startup but even among white collar employers tech companies generally have top-notch health insurance.
I'm not talking about monthly premiums, I'm talking about what it costs when you actually need health care. How much is the deductible, what is the coinsurance rate, how steep are the co-pays, how weirdly restricted are the options for doctors, etc.? "Zero cost full coverage" sounds like the old Microsoft plan, where everything was paid for all the time. That defines "top notch" for me, and most health insurance plans I've experienced are nowhere close to being that good.
I think you're exaggerating the actual cost. I really don't think Google has a deductible plan, and I'd be surprised if the copays are more than $10 or $20. And remember, we're comparing this to Canada where you still have to pay for prescriptions (or at least a co-pay depending on your situation). Very, very few countries in the world actually cover 100% of healthcare costs.
All in all I don't really think it's a useful point of comparison when considering compensation between the two countries.
I wasn't trying to compare countries; I don't know anything about Canada's health care system. I'm just taking issue with the assertion that "the healthcare coverage you will get from any tech company paying 6 figures is going to be essentially zero cost full coverage", because that isn't, according to my experience and observation, actually true.
