You have no theoretical base. You are regurgitating a political ideology that is, quite frankly, nonsense. You focus on demand, when it is irrelevant to this discussion, and your argument presumes that "advising people to save is bad" because "if everyone saved there would be no demand".
Obviously, when people run their lives prudently, they don't eliminate all spending (and thus all demand is not eliminated). Obviously, consumers are not the only source of demand in an economy. And obviously you can't really defend your point and that is why you spend your time characterizing others -- and in fact your "economic" argument is really just disparaging a savings plan with a fallacious -- but oft repeated by political hacks-- story.
So, of course, I was dismissive. Your "argument" was easily dispatched.
How many economists does it take to change an ideology?
