That's mostly the fault of the Republicans. After the crisis of 2008 we could have bounced back using either fiscal policy or monetary policy. Congress could have spent a few trillion in stimulus to get the economy back on track. By 2010 it was clear that the initial stimulus of $800 billion was not enough, so further stimulus spending should have been a high priority, but the Republicans blocked further fiscal action. That meant that the Fed had to do all the work, using monetary policy. We didn't get the kind of big stimulus spending we needed till 2020, when President Trump finally pushed through several trillion in stimulus spending in the face of the Covid-19 pandemic. But for years after 2008, the Fed had to do too much work, with monetary policy, because Congress was doing too little with fiscal policy. It would have been healthier for the economy if we'd had fiscal stimulus in the real economy rather than monetary stimulus in the financial economy. Wages would have gone up much more with fiscal stimulus.
