The BLM protests and riots were pretty close to a revolt. But it was a revolt against the abuses of the criminal justice system and did not extent very far past that. That is why you saw all the big businesses embracing BLM with donations, pro-BLM PR campaigns. Amazon donated $10 mil because it was afraid that BLM would expand out to include economic justice issues.
The current political elites have done an excellent job (objectively speaking, not normatively) of creating political narratives that keep the working class from uniting and revolting against the economic and political system. Trump convinced the working class that the reason they did not have jobs was because of China and immigrants and that Dems only cared about identity politics. There was a kernel of truth in all of that, but Trump never had any intention of actually doing anything because Trump's big business supporters love free trade and cheap illegal immigrant labor. So, Trump just put on a show with a tariff here and being cruel to immigrants there, but accomplished nothing. This is largely why Trump lost. He did not deliver and enough people saw through his dog and pony show.
Dems have pretty much embraced the old conservative narrative that people are individually to blame for their circumstances because they did not do well in school and deserve to have less than the people who went to good schools and became professionals. The centrist Dem answer for everything is to embrace the meritocracy and make it more equitable with half measures like tax credits for community college tuition and to soften the blow of the markets with minimal safety net programs like WIC.
The Sanders/AOC wing of the Dems offers the only real political voice for revolutionary change, but they have failed to get working class voters to come out and support their movement. This is mainly because the working class has largely accepted either the Trump narrative or the centrist Dem narrative and either believe that the system is just fine and we just need to do something about China and immigrants or that they deserve their lot in life because they did not do well in school. But most are just apathetic because over the course of their lifetime they have never seen an example of the government delivering any benefit to the working class or the working class ever using the power of withholding their labor to gain power and concessions from the ruling class.
So, the answer is that until the working class realizes that their labor is power or the progressive dems get enough power to deliver real progressive programs, you will not see any sort of wide spread revolution in the US. There will be spasms here and there, but people are too divided (purposefully) and to beaten down to get any ideas about taking action against those who oppress them.
