If you earn no interest and expect to spend $6000 a month forever without ever gaining any passive money accumulation on your principal, you'd go for 27 years before you'd spent your two million.
There are also many things you can do with your life if you have $2M (or indeed $1M) that aren't available to pensioners. I'll grant you, they've got some pretty sweet pensions: that seems unusual, but hey, collective bargaining gets better terms for workers and that certainly qualifies.
They're not poor unless they're catastrophically bad at money management, but you are indeed a little out of touch: the idea of living off the interest on your wealth is pretty insane and unattainable to any remotely normal person.
