Most countries with universal healthcare are not paying 45-50%, that is really only a few countries that also have huge safety nets and public services well beyond healthcare (not to mention the Americans spend more on healthcare costs than other country on earth). If you want to show the math state by state and country by country, you better sit down and pay some tuition. When you are paying 6-15 GRAND in healthcare premiums each year, you better believe no one in other countries have this burden. No one moves to the USA to escape taxes or reduce their tax burden, it just doesn't happen. Personally speaking, I have lived in about a half dozen other countries (although I am one person, and this is purely anecdotal), the USA is one of the highest burdens with regards to taxes and income reduction I have encountered. This nonsensical American exceptionalism, where we can't compare it to any other country, because "apples and oranges" is a defeatist attitude, and a flight from the reality on the ground.
