yes they tried that in Turkey, president’s highly incompetent son in law was made minister of Finance. At the start (2018) of this I think pounds/Turkish lira was sth like 4. He stayed for two years and it ended with maybe something like 10-12. As of now it is around 50 (people after him weren’t that great either). Since nowadays production of almost anything in Turkey is tied to imports, prices of daily consumption goods as well as rent, housing etc went up by that amount too (salary increases not even comparable). good luck USA
The funny thing is this sweep will likely be very indiscriminate so among those fired many will have voted for Trump hoping groceries will be cheaper. They will learn first hand what happens when you entrust government to psychopaths and techbros.
