Very beneficial/interesting discussion.
I learned that as a citizen of the USA, my taxes are lower, gasoline is lower ($3.19 USG), I pay less for food & utilities & housing. So I guess I'll quit bitching about my taxes. My State has an average of 8% sales tax on most items, but only 3% on food. Some States have no sales tax. Others have no State income tax. But I think we have higher cost for medical care and esp for Rx drugs.
For comparison purposes, I have a 4,000 SF (370 SM) home w/ 5 bedrooms & 5 bathrooms on 1/3 acre. Because I live in the Midwest where the cost of housing is lower than either coast, it's value is about $500,000. On either coast, it would be double, triple, or quadruple that value. My home's monthly utilities (water, electric & gas) totals about $300/MO. We have 5 cars. My highest mileage car gets 22 mpg. My lowest gets less than 10 mpg and requires premium octane gasoline at $3.59/USG but I only drive it about 3,000 miles per year. We are "middle class" (some might think "upper middle class"), but certainly not exceptional. Professional people (doctors, lawyers, engineers) earn far more than I. In the USA about 20% of working individuals earn over $100,000/year. Those in the top 10% usually earn over $250,000/yr.
I'm afraid I know very little about how that compares in other places in the world.
