Any idiot with a spreadsheet can do "cost-cutting" by outsourcing to China, hiring illegals, using cheaper inputs and destroying customer service. They don't care as long as they have the backing of those providing ready capital on Wall Street, who also benefit from short-term gains but get out early.
Few see it, for years I have had that understanding. The arguments on this issue usually pick one of either side and in truth both sides are wrong. Hard to get people to see that.
The current concept of “shareholder” is anything but for the shareholders, it is a mechanism to dilute and ultimately remove power from any accountability of the owning group and instead give it to the “manager” you have identified. This ends up in control of a few globalist elites. It is basically stealing the power of the people who think they have a vested interest in the business.
Also, as you identified this then allows an unaccountable series of cost cutting measures to tear the company down to the detriment of the employees and the legacy of the business.
