Back when GM first started being a company, GM introduced planned obselence, so consumers would buy cars more often. GM also paid its workers 5 dollars a week. GM didn't stand behind their product and would often say buy a new one.
Ford on the other hand planned for cars lasting longer and tried to come up with retail parts cheaper and a supply chain for them. Ford paid workers 5 dollars a day. Ford buisness principals were copied by Honda and Toyota.
GM will always want a govermnet handout. GM has always expected a handout and GM does not wish to honor its warranty. Is that really the way to run a buisness?
