The company had already been created. His heirs didn't have to spend their money to hire you.
Completely irrelevant. If the heirs had closed the plant down, and flown to an island to live out their days sipping martinis on the beach, served by bikini clad serving girls..... guess what? 20,000 wouldn't have a job.
So the fact they keep the company going, whether it was already built or not, does make any difference.
And forget the heirs for a minute. Whether they are directly involved in the company or not, doesn't matter, because ultimately there is still a rich person, as CEO of that company today. Richard G. Kyle is CEO today, and he's rich. If it wasn't for him, there would be 20,000 fewer employed people.
Rich people create jobs. To doubt that is absolute stupidity. You think the Timken roller bearing plant would have popped out the ground, by itself, without a rich person funding it? That's like going home to your wife, and finding a full 3 course meal on the table, and thinking that it all happened because someone threw a grenade in the kitchen, and out popped a meal.
Ridiculous. Leftism, is the ideology of ridiculous.
