To my knowledge, he made his kids learn the business from the bottom up, even learning to operate heavy equipment.
Nor am I aware Trump claimed to be lower class or middle class - but he relates to lower and middle class people in his speech patterns, etc. They like him.
In running a business, you are supposed to make a profit. You create value that people will pay for. He has done that.
Frankly, had I been born into his economic position, I do not think I would have handled it as well.
It’s still disingenuous.
I will say as far as being good stewards of business, Trump did an excellent job with his Ivanna children. Don’t really know about the others.
