All billionaires are right-wing. They uphold and embody social inequality. Whether they endorse rigid social divisions along cultural lines is just extra gravy.
Democrats are right wing by the standard that they uphold social inequality. They certainly market themselves as left-leaning, but if I had space and sufficient interest, I could easily discourse about the ways in which they are anything but.
Most politically visible Americans yes. People in other countries hold different perspectives, especially in former colonies. People that don't benefit from social inequality (i.e. the majority) are relatively easy to convince the system doesn't work for them.
Not sure about their beliefs. I suspect they just endorse the party most likely to give them a tax break. This may also explain why many are going against Trump - he's been telling the public they've been given a bad deal and he's spoken against some big pork behavior. Who knows what he might do. Biden OTOH seems business friendly enough.
Only if you consider everyone that does not support full on Authoritarian Communism "right wing", and allow for zero classic liberals, libertarians, and 100's other world views.
This is the problem with the narrative on the internet today, anyone that is not collectivist, is not full on Socialist must be "Right wing"
During the monarchy, liberals were left wing (the "radical republicans"). After they won, liberals became the defenders of the status quo and are thus the right wing. There are people further right that wish to roll the clock backwards.
The Radical Republicans refers to a group of anti-slavery congressmen in the 1800s up to, during, and after the American Civil War. There was no monarchy at the time.
That was one later instantiation. Republican radicalism was feared by the aristocracy in the 1700s-1800s. Perhaps they weren't uniformly called "radical" but republicanism was hated.
The group you're referring to was part of the "Republican Party" which was created after republicanism was victorious in the united states after the revolution. I'm not intimately familiar with the iconography around that period, but I would speculate that they were drawing on the old symbols of radicalism when creating that name.
