I shall tell a story...
A local company was having staff shortages over the pandemic. Couldn't get entry-level people to start, such positions went unfilled while people rode out the unemployment and the extra $300/week incentive. Company raises wages for entry-level positions by multiple dollars an hour, but no one else. Someone who worked there six months now made almost as much as someone who worked there six years.
Those seasoned workers (who didn't get the raise) left for other companies or got themselves fired to take advantage of the unemployment. Due to the vacancy of those seasoned workers, the supervisors had to drop back and fill those tasks. Supervisors weren't able to do their job and morale tanked (as if it hadn't already) and soon most of the supervisors quit.
So now, that company has several open positions that they're struggling to fill, entry-level positions pay too much, no one wants to move up, and there are no supervisors. Advanced level positions are now being filled from the outside. Finally, after all this, the company gave everyone else a raise to stop the bleeding.
Maybe not a case of too much money, but an imbalance.
