I am guessing that a lot of these big manufactures in all different industries are running a just in time inventory system. when this covid thing started it was just a matter of time to screw everything up. it was inevitable. all inventories from there suppliers are used up. the suppliers now cant get material to make the parts for the end user. and now all the consumers get hurt with higher priced and longer wait times. from the beginning of covid til now is how long it'll take to maybe get back to normal. that is if it doesn't get worse than it already is. Hopefully I am wrong.
