Yes, this is hypothetical. But let's have some fun.
Let's assume that for a one time fee, you could roll back the size of all levels of government in the US (federal, state and local) to what it was in 1955.
There would be no "great society," no medicare or medicaid (health care costs at this time were very modest and most people never bothered to even think about insurance), no EPA, no OSHA, no DEA, no RICO, no NAFTA, no GATT, no wars, and very modest taxes (in real terms) compared to today.
And yes, you would live in today's world with all of your high-tech gadgets.
The question: What is the MAXIMUM one time fee you would be willing to pay to roll back all levels of government this far?
