Not necessarily, there are major disparities within the US health system (a well as within others). We have the best resources here, but it doesn't mean that every person or every region enjoys them. Some are concentrated in major metropolitan areas.
Additionally, although our "best" might be better than their "best," that doesn't mean that the median level of care is any worse. For instance, try getting non-emergency care when you can't afford the deductible.
Furthermore, in health systems with lower costs at the point of service, an individual is not economically deterred from seeking early treatment. In the US, many of us have to "wait it out" to see if the condition passes because the treatment is too expensive. In these cases, we are essentially gambling with our health.
I will use my health plan as an example. When the new fiscal year starts, we will be paying over $500 per month for family coverage. My employer is adding around a thousand more per month. We are paying over $18,000 per year. What do we get? A $1500 per person deductible!
To drop the deductible to $500, we would have to pay around $300 more per month.
We cannot pursue an option in the individual market, as the benefits are even worse, the cost is post-tax, and pre-existing condition exclusions greatly reduce the utility of the insurance policy.
This is simply unsustainable. I don't believe for one minute that the health reform will do anything to substantively change the problems in the system. Something needs to be done, however.
