Why progressives cave

This article makes the case that the reason progressives have been mostly conciliatory towards Biden is because at least they are getting a seat at the table. But as usual they are getting shut out of actually getting their proposals, highly popular with the majority of Americans, included in legislation. 

Biden and the establishment have also been good at the public relations spin, telling progressives that they need to surrender in the name of Party unity, and it they don't they are the ones to blame for election losses. This despite the copious evidence that they win when progressives stand firm on issues the majority of voters support.

Unfortunately, and with rare exception, many progressives still hold on to that false narrative believing that the Party will come around to their proposals when faced with public pressure. They just can't wrap their heads around the fact that the Party only cares about itself, not we the people. And the cost of that denial is apparent.

"Criticism has been in surprisingly short supply during Biden’s first six months, from a left flank that’s been somewhere between docile and unctuous. D.C. progressive groups have lavished praise on Joe Biden as the next FDR, and when he’s indulged some un-FDR-like tendencies, they’ve continued lavishing. [...] The result has been a progressive flank that has been defanged in Bidenworld, unwilling to make public criticisms even as much of the legislative agenda has slipped away. Already, gun control, judicial reform, student debt relief, and much of health care and immigration reform have fallen by the wayside. Policing and criminal justice reform has bogged down in seemingly endless bipartisan negotiations, with Biden pushing no deadlines for action. Democrats have split on drug pricing, with moderates on the Hill chasing modest tweaks and progressives trying to go big to save hundreds of billions for additional fiscal spending. Tax reform, despite making it into the reconciliation bill, remains on the ropes. There’s no real plan to pass meaningful voting rights protection, which Biden admitted preemptive defeat on in a July speech. The PRO Act and some small percentage of immigration, like the $15 minimum wage before it, will be decided by the whims of the Senate parliamentarian. The president himself is one of the stronger remaining defenders of the filibuster. Yet the self-censorship and happy talk endure."
