There are plenty of never-profitable businesses that have gone bankrupt in the past. See e.g. pets.com from the dot com bust. And this downturn has seen "functioning" businesses like SVB and First Republic go under too. So I'm not sure this time is different, at least to the extent you're suggesting.
I do agree that this era of low interest rates has led to some companies getting absolutely massive without ever turning a profit. But hey, that playbook worked for Amazon. Most tech companies have substantially lower capital requirements than WeWork, and can weather this sort of downturn as long as they have a reasonable cash position. Sure, Uber might not make back the amount of funding it's burned through, but that's different than it having a business where the unit economics will never work out.
You write in a tone of contradiction, but I'm having trouble understanding how your points relate to mine. I don't believe I said that never-profitable businesses were unique to this era, or that the only business failures lately have been ridiculous ones.
I also think Amazon is distinct in that they chose to not have profits because they saw better uses for the money. Bezos could have declared big profits long before he did, and there was a noisy contingent of investors who were agitating for it. Bezos instead chose long-term investment in ways that upended our notion of commerce, and whose effects are still playing out.
I think that's very different than WeWork and Uber, where a lot of investor money was burned on subsidizing the core business. At least in Uber's case there was a theory, which was basically, "Use the rise of mobile to capture the global taxi market (while externalizing the capital costs to the desperate) and then use pricing power to extract Google-size monopoly rents." Maybe not a great theory, but at least something articulable. Whereas WeWork never made any sense as a business beyond a hazy "Uber for offices" handwave.
Amazon is perhaps one of the best executed businesses. Their retail logistics physical footprint is insanely huge and chews billions in capital. They chose to reinvest their profits to stronghold their logistics position.
