He can never be classified as a greedy man, take a look at it, he owns the company like you said if he stays at home he still makes his money nothing changes even if he goes to work. He pays the workers he's in control and he can make a call for all workers not to come to work for as long as he desire, so I can't place a man with such right over his work as greed except he starts making life a living hell for his workers like not paying them complete salary when there's enough money to do so, that's it.
I think this is normal because the goals of private companies are like that and it is not an easy task and the company also does not want any financial losses, meaning they always maintain the company's performance. The main boss in a private company generally has a concept like this, how much income can be generated to increase the company's profits at the cash close at the end of the year even though he does not work on site.
It is just. The hope that workers need from their superiors is that their superiors are able to create balance, meaning that they must also be fair and responsible towards their workers rather than their share of workers to continue working to generate income
