This video reminded me of what happened to Filmation, an animation company in Southern California. At different times both my wife an I worked there, along with a lot of other people working in the animation industry. The company was owned by Westinghouse and did reasonably well under a policy of benign neglect. Then Westinghouse took an active interest in Filmation, resulting in layoffs and decreased production. Then there seemed to be a glimmer of hope. There were rumors the French cosmetics company, L'Oreal was going to buy and rejuvenate the company. L'Oreal did indeed buy Filmation, and immediately fired everyone and disbanded the company. What L'Oreal wanted was the film library of He-Man, She-Ra and Fat Albert episodes. The people working at the company were so much excess baggage.
Regardless of whether the video is valid or not, the policies of the Republican Party from Reagan onward have resulted in the steady erosion of the American middle class. Some investment in the country is needed, for example, a program to rebuild the nation's physical infrastructure - but don't look to the Republicans to initiate such a program.
