A single word: incrementalism. Biden has been in the government power structure for many years and represents the glacial pace of progress over decades. The frustrations have grown more palpable after seeing humans in absolute crisis in so many cities.
People are living, suffering, fighting out, and dying dismal lives without access to shelter, healthcare, and other resources necessary to live, let alone thrive. Many are employed, but still struggling.
The plutocrats are the masters. No matter how much productivity the plutocrats receive, the benefits aren't seen by the working class. The two-party system is backed and influenced by this plutocracy.
For those with student debt and/ or medical debt the deferred treatment and the dearth of social climbing can induce a panicked spiraling.
This is an overly long way of advocating for more than incrementalism. Humans deserve their basic needs met if they are sacrificing their lives for bloated corporations.
