It is hard for the reality-based community to understand people who exist in their own imaginings. To be out of touch isn’t just to exist in an ineffable present; it is to be unaware of tangible reality. Think of them as moving toy soldiers through a military engagement that is all fantasy. On Capitol Hill they are moving piles of money around budgets in much the same way.
All their maneuvering is totally disconnected from the real world. So, expecting Congress to be aware of real life consequences is an exercise in futility.
How did we end up with a bunch of game boys? We allowed ourselves to be impressed by the fact that they speak English. And, unlike a talking parrot, they look just like us.
