I agree that the article is misguided on several levels, including, as you point out, that the ‘Greatest Generation’—a moniker that nobody would have dared trot out while the WWI vets were still around—is largely gone now.
What he’s getting to re: our elderly bankrupting the country with the level of, particularly, healthcare benefits that they are receiving from the government is a fair one, but it is put into poor context here.
I think the illegals and non-citizens should be addressed first.
