From the 20th century, we have the ideological war against USSR to thank for that. It started all the way back with Wilson. After WWII, the threat of nuclear annihilation was a powerful tool for nationalism. (I’d learn only recently that a first strike was far more likely to come from US than USSR, and we had some dangerous war hawks in power.)

Before that, after reconstruction came redemption and corporate interests took over both parties.

Before that, roads, schools, bridges, libraries and such were socialism giving the working man benefits to which they didn’t contribute (we just contributed all the labor). Yes, they called it socialism even back in the 19th century.

Do observe that adherence to neoliberalism in the EU (which is essentially corporatism with extra steps) is driving the rise of far right movements even over there. And when the tech-bros and white Christian nationalists over here are done bleeding the US dry like its private equity, they’ll be headed over there with their vast wealth to do the same thing.
