Don't forget taxes. If your total taxation rate is more than 50%, then you're spending half your working hours for yourself, and the other half working as a slave for the government.
Add up income taxes, property taxes, sales taxes, payroll taxes, etc, and it goes over 50% pretty quickly.

And the other half helping build the infrastructure, services, protection (army), education etc that enabled you to live and work in a sovereign, developed country in the first place.
For example, approximately 0.5% of the NYC population works for the NYPD. So, a tax rate of 0.5% should be sufficient to maintain order in a city like NYC. Add in some overhead and you get to 1%.
Roads are similar, can be done easily for 1% or less.
As a European, I don't think the US would be anywhere as developed and top dog without the "military/industrial complex" ensuring it get its diplomatic way, cheap resources and favorable deals around the world.
