In any case, the resulting individual "burden" is meaningless if you don't also quantify individual benefit. As an extreme example, imagine a country in which your income taxes pay for things such as transportation credits usable on gas, public transport and roads, while the neighboring country has mostly private toll roads and low taxes. Another example is health insurance. In Germany it is pretty nearly mandatory with most having some form of insurance, and total spending per citizen is around $9,000. In the US more than 90% are insured and spending is higher, but within the same ballpark.
What does the raw tax/burden tell you here in an international comparison? Fuck all. It's at best usable as a prompt for a philosophical discussion about autonomy, but often merely used for masturbation or making dishonest arguments designed to go over well in establishments specializing in alcoholic beverages - like those of a certain interest group.
