Keep in mind we're the last effectively communist country in the world, I'm not surprised in the least to see corporate taxes up there with the "banana republics" gp was talking about. "Social" money has to come from somewhere!
We have extremely influential labor unions, the public sector is a leading job provider (even a majority employer in some areas), healthcare and a lot of infrastructure is nationalised, huge welfare programs, free public education for all...
But most importantly to the (joke) argument that we're the last communist country there's a massive popular adhesion to the points listed above and for some reason a deep seated mistrust of the wealthy.
I mean, you only have to look at pretty much every wealthy person to see why they would have a mistrust of them. Even guys who are doing good things now, like Bill Gates, didn't get wealthy by acting like nice people.
As for the communist thing, ah I didn't realize it was a joke argument, thought it was a serious one
