The only difference today is that after years of taking the votes of reactionaries and doing little, the populist blocs of reactionary voters are the tail wagging the dog.
There are (outside of small local cooperative enterprises) approximately zero left-wing companies in the US.
The things painted as “left-wing” companies by the far right are center-right neoliberal corporate capitalist enterprises that do some mix of opposing far-right culture war efforts as a drag on corporate capitalist exploitation and making PR gestures to the left side of culture war fights while remaining locked in the economic center-right.
Yeah, in the GOP’s current view of the world, the U.S. Chamber of Commerce is considered radical leftists, but, that's not reflective of reality.
Where do you think ideologies come from? One of the most common places is some identifiable group's economic self-interest; neoliberalism is that for the owner class in capitalist society, which is why institutions controlled by that class (especially when they are controlled broadly by that class rather than by an individual member who may have personal quirks) tend to pursue it.
Even Trump supporting farmers were complaining about not being able to find anyone.
Just like they were all for the wall until the government started using eminent domain to take their land to build it.
It's the same thing with climate change on the left (Democrat politicians never manage to pass any kind of carbon pricing because they know they'd get crucified by business interests), but I wouldn't say that the left-wing broadly opposes carbon pricing.
The left wing does not, and much of it actively supports it.
The Democratic Party-in-government, dominated by its center-right faction, does oppose it, or at least does not actively support it.
