Some people who have reached their retirement age they do work it out to extend their stay in an organization they find themselves, I don't know if I should call it greed or not but is like they enjoy what they gain from their place of work and is hard for them to let go.
I don't think is only women who pray to retire so they can go look after their family, some men do have that thinking also, in some cases some people who are not satisfied with what they're seeing at work just see retirement as a way to get out of working.
Don't consider every person who is still at work when they reached a retirement age; as greedy, like I said in my last or previous comment, what is keeping them in that office could be passion, that is, love for what they do, we have many people like that.
Here in my area, I know of an old man who still goes to work, he owns the company, has more than enough money to just relax and enjoy life before he dies, but his driver still drives him to work every day from monday to Friday..
Can you still say this man is greedy? Of course not, he owns the company like I said, if he relaxes at home, he wil still be making his money, but then, he decided to keep working, possibly because, he loves his job as the CEO of the company, and having to relate with his workers every day makes his day fulfilled. So many people are like this.
I get your point but I'm not really pointing them as greed per say, is just that whenever it's time for a worker to go he or she have to go, where it has to be as the act of greed is when they do push the time or year of retirement forward, like a worker is suppose to retire by 2023 but he or she had to work it out to be 2026 that's where greed comes in. And if it's time you make way for others to come in, younger ones to have a feel of that organization too, it mustn't be you, you know? Let that love and passion be.
Speaking about the man you said owns a company, that's a different things, he's the boss and nobody can serve him letter of retirement because he's old which he knows. My company my business I do whatsoever I do please, the other workers would respect that and nobody have the right to query him on his decision of still coming to work. He can decide to serve the driver a retirement letter and that would stand, but as the owner of the company everything is under his care and control. And him going to work is not to do much but to relaxing.
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.
