Why is the American infrastructure so expensive to the average citizen?

I've been comparing the cost of living between countries, notably those of Western and Eastern Europe, China, South Korea, Japan, Australia, India, and Southeast Asia. And I am wondering why everything is more expensive when we don't even have many things that most of these countries already have (not all, but most), like universal healthcare, high-speed Internet ($10 a month buys you 100Mbps in Korea vs. $70 a month for 15Mbps in Washington DC), cheap housing, cheap public transportation. Where is this money going?! Obviously not wages because average income in Western Europe, Australia, Japan, and South Korea are mostly similar to ours.
