Recent polls suggest majority support for tax-based measures addressing wealth inequality. E.g. this one from March:

"Fifty-six percent of registered voters in the March 5-8 survey said wealth inequality is a significant problem facing the country and billionaires paying a wealth tax is a part of the solution."

I don't have historical poll data at hand, so I don't know how this has changed over time. My impression that it's become a more popular proposition recently (since the start of the pandemic) might be wrong.
