Earlier quoted context omitted.
> removing people and organizational slack You are spot on w.r.t every assertion you've made. When bean-counters took over the ecosystem they optimised immediate profitability over everything else. Which in turn means, in their mind, every part of the system needs to be firing at 100% all the time. There's no room for experimentation, repair, or anything else. I've commented about lack of slack on several times here…
> optimised immediate profitability over everything else Which is the usual complaint that businesses are focused on short term results, sacrificing long term results. If that would be generally true, the stock market would be going down steeply, not up, as stock prices are based on expectations of future profits.
Besides that, the U.S. stock market went up over several decades while manufacturing capabilities were transferred overseas. That has had, and will continue to have, domestic ramifications that might not be captured by investor profits.
