Should we have a parallel thread about all the things that government messed up? Or just include it here?
Zoning laws and interstate highway program that has led to suburban sprawl and an over reliance on personal transportation.
Subsidizing corn and the thus encouraging the development of high fructose corn syrup.
Most nutritional advice given in the last 50 years loaded with influence from special interest groups.
CAFE legislation that encouraged automakers to market SUVs to get around the regulations.
$686 billion in military spending for 2019
Just to give the libertarian side also, how much of this has occurred in the last 50 years? Sure some of the tech stuff is fairly recent but also arguably not 100% dependent on government for development. And when you confiscate 20% of economic output, you better have something to show for it.
Preaching to the choir about how great government is only has so much value. Pretending that the majority is willing to pay more taxes doesn't really help. I can't tell you how many liberals I know that spend a lot of energy avoiding taxation and drive diesels and SUVs. And when I say lot of energy - I mean things like moving to low tax states.
