But also there were actual benefits to loyalty that don’t exist anymore. Labor union participation was huge in the post WWII, pre-Welch time frame. They used that leverage to negotiate benefits, many of which rewarded loyalty. Pension plans vs 401ks, significant pay raises based on seniority, clear paths to promotion, job security prioritizing senior workers, etc. Those things permeated through job markets and companies without unions as well, given the labor force competition. People were loyal because they had real tangible compensation and benefits for it.
I think another shift around Welch was that companies used to focus more on long term value, which would result in stock price increases in the long term, even if not in any given short term. That if a company was healthy and valuable, one of the many benefits would be rising stocks. The shift to focus on short term stock increases as almost the only goal, means companies will pull the copper piping out the walls and destroy the house if it means a juicy bump in the Q3 earnings call.
