Total Tax Revenue
US taxes are relatively low compared to those in other developed countries. In 2015, taxes at all levels of US government represented 26 percent of gross domestic product (GDP), compared with an average of 33 percent for the 35 member countries of the Organisation for Economic Co-operation and Development (OECD).
Among OECD countries, only Korea, Turkey, Ireland, Chile, and Mexico collected less than the United States as a percentage of GDP. Taxes exceeded 40 percent of GDP in seven European countries, including Denmark and France, where taxes were greater than 45 percent of GDP. But those countries generally provide more extensive government services than the United States does.
Why are US taxes relatively low?
The answer is pretty simple, and already got answered in the paragraph above. Other countries offer more extensive government services than the US, which inlcude but are not limited to: Free Healthcare, Tuition Free College, no need of purchasing unemployment or disability insurance (as they are already covered by taxes), etc. All of those services are packaged and delivered by the government in most european countries, and here in the US you have to pay for those services whenever you need them.
Which option would you choose? Would you rather pay higher taxes and take advantage of free government services, or would you rather pay relatively low taxes and pay for those services whenever you need them?
