I'm almost confident that someone else out there could make a similar speech arguing the opposite point and be just as right.
IMO, If you have a company owner making $500,000 a year in wages and profit, way more then what is needed to live comfortably, and has 100 employees making $30,000 a year. The owner could certainly help the economy by giving those 100 people a $1,000 raise which would get that money back into the economy, or hire 3 more people at similar wages to create more jobs. He would still be making $400,000 a year in my eyes would still be a very comfortable salary.
The main impression I get from his speech is that he is trying to justify the rich in keeping their money.
