Yes, he spent his whole livelihood "working". And you can see Trump's work ethic reflected and magnified in his children.
According to his children, their father lives for work.
They despair because if their father becomes Emperor, trips to Hawaii, or trips to go fishing, will be outlawed as "frivolities". Golf, however, will become the national sport, on the plus side. /tongue-in-cheek :)
I think what Trump inherited from his father was the work ethic. I respect that greatly. I like the business acumen, too. :)
His children are very impressive. I wish they were mine. More then I would like his wealth, I would like his success with those children of his.
