Not taking a position for or against WeWork but I'm not sure that they are particularly flashy, especially when it comes down to the actual office space away from the common areas stocked with beer. What they do offer is some level of consistency and predictability, and there's something to be said about that.

As a side note: The airline analogy isn't correct. Business and Premium Economy products are doing quite well with growth of those two offerings having been quite robust over the last 20 years. I'd say belt tightening did happen, but with respect to first class fares. Easy fix...just rebrand your old first as business!
