It came from Biden reducing oil production. That increased the price of diesel and gasoline at the pump, thereby increasing costs for manufacturers to transport their goods to stores. Guess who got those increased costs passed on to them.
The inflation in housing came from Biden increasing the population in cites, where he transported migrants to. They saturated the housing market, making vacancies scarce.
The dude ruins everything he touches. Would have been better if he just did nothing at all.
