Left vs. Right largely boils down to "are hierarchies good?". A quintessential far-right belief is the divine right of kings. The modern incarnation of that is that "The 1% earned their power and influence".
Now, there are far right people who want to dethrone the current powers that be. But distinguishing between "I think Mark Zuckerberg shouldn't be given unlimited power because no one should have that much power over others" (left) versus "I think Mark Zuckerberg shouldn't be given unlimited power because he's a Jew" (right) is a useful distinction. One wants to eliminate the power structure, the other just wants different people in it.
