OP, I think I get what you're saying.
What this guy is doing just seems so wasteful doesn't it?
If you're physically capable, if you have the time, to sit on the computer and b and moan about things... It annoys me. But then I think, why does it annoy me? What difference does it make to me what he's doing? Why should I be fussed?
And true, that is the correct answer in so much that I should keep my nose out of other people's business.
I have a neighbor that does the exact same thing. He's physically capable, late 70s, financially well off, and has nothing to do all day but putter around and make sure that his bit of property looks absolutely proper. Not a single leaf out of place. (You know the type. )
Me? I'm not tooting my own horn, but I volunteer all over the city. I pick up garbage, I build feral cat shelters, I volunteer to help seniors, I volunteer to assist children. (And that's when I'm not working.)
And I think, there are so many people like my neighbor, who do nothing for anyone but themselves. They have absolutely nothing else to do but sit there in a chair in their driveway and hope a visitor comes...and if they don't, they spend their time chasing away any squirrel or any bird, pick up any leaf, sweep away any dust, and make sure their property looks absolutely perfect. For whom? (No one. Because no one comes to visit them because they're not a very pleasant person)
And I think, wouldn't they be happier if they could take some of that energy...they have the mobility, the time, they like making things spick and span, wouldn't it make so much more sense to be able to help others? Work in a community garden where the food gets shared with less fortunate, pick up garbage from parks and roadsides, take some of your talents and build something that can be used in the community? It just seems like such an incredible waste.
But that's the way they choose to live their life and that's what they choose to do with it. It would make so much more sense and be so much better for everyone if we would all help instead of being selfish but, it's their prerogative to do so. It's their life and they don't have to help anybody if they don't want to. They don't have to give any of their time, any of their skill or any of their money to anybody else because that's their choice. It's not nice, but it's their decision and, I can't say do or think anything against it.
If this is what you mean, OP, then that is what I understood by your post.
If you meant something else, then I misunderstood.
Try not to let what others do bother you.
I know it's hard.
