It's a very good thing, a nice thing, a great thing. But, there is always a but. Do you really think he just gave it to them, with no benefit? What about running the business, can they do it? What about taxes that they will have to pay? If the business fails, who do you then blame the guy who gave them the business or them? It all sounds nice and dandy until you really look into it. After all, he is retiring, he got what he wanted out of the business and all those "rich people are bad" sort probably spent days criticizing him for being successful are now saying he is so nice and wonderful.
And please, last time I check they worked for him, they didn't build it - they got paid, they followed orders, they were promoted or fired based on their work and they had benefits - they agreed to the exchange: you pay me I work. They didn't built it. How many of them took out loans on their homes to start this business? How many of them went to work for no pay when the business was in the red, losing money? How many of them left when they found a better job? Please.
The man did a nice thing. I am not sure if it didn't cause them trouble, because being an owner is different that being a worker.
