They wouldn't, you're right. We will not see the NYSE shuttered in the next 4 years or Amazon's excess of revenue over expenses taxed at 100% and their money bags driven across the country in armored trucks and heaved into Elizabeth Warren's US Treasury as a result of this election.
On the other hand, despite the fact that my tongue was firmly planted in my cheek when I wrote it, such Debbie Wasserman Schultz haters as Nathan J Robinson and Noam Chomsky have adopted the 'Vote for Biden and keep protesting' angle so who's to say how the real socialists are voting this year?
