This is my problem with economics. You’re talking about theory and practice as if they’re the same thing.

Way back when, I used to sell computers and computer parts at retail. I assure you this was a regular conversation topic. "When is the Voodoo 4 graphics card coming out? 4 months? Okay I won't buy the older Voodoo 3 now because I can make do with my Nvidia TNT2 until then."

All consumers do not make perfectly rational choices.

No they don't, nor or do they need to if you're taking a macro view.

Hell, most don’t.

Are you saying:

• consumers NEVER make rational choices?
• consumers don't make 100% rational choices 100% of the time a choice is available?

I disagree with the former, but I agree with you on the latter. None of that invalidates micro or macro economic theory.

This kind of theory only explains how rich people want you to think things work. It’s not how things work in the real world.

Many rich people get rich because this works. They also play dirty tricks to create the situations, but then again in those situations the theory works.

I'll be the first to say economic theory is far from perfect and the deeper you go, the more complex, and potentially less reliable, it gets, but the basics are pretty sound.
