The right has elements of populism but serves the owner class. The left has a progressive wing that's basically powerless. In most other democracies these elements would be aligned in a progressive green party. But split as they are in the US, they're powerless.
Under Obama, Democrats had a veto proof majority for 2 years and didn't do much to help income inequality. Trump talked a lot about helping blue collar workers but similarly did nothing. I'm afraid both parties are too corrupted by big business
Both the parties server the same ruler. All the news and "issues" at hand are just distractions to divide and conquer.
Look at how quickly Biden's minimum wage increase got smashed. More interesting, look at how some populists on the right are also calling for it. And look at how populists and progressives on both sides are asking for regulations on big tech.
The progressive wing is split. Trump picked up a ton of voters that were mad Obama didn't help them. These voters otherwise align more with Bernie Sanders and AOC. You'll notice some MAGA voters have a begrudging respect for those two. It's because they honestly want to help people, reputation be damned.
The US is on a path towards oligarchy unless the voters can shake our parties free from their corporate overlords.
