The US is allergic to taxes. Maybe it's a marketing thing. Benefits paid for by society.

Maybe a department of Return on Investment. See what those taxes pay for. Contrast to buying private versions of the services at the same SLA or better.

It’s more that the US is more like a collection of 50 little countries, and it’s supposed to be hard to accomplish much at a federal level. That separation has eroded a bit in the last 50 years but it’s still very much a part of our political ideology.
