The key is, politicians, of any stripe, rarely comprehend economics, and even if they did, wouldn't let it change their initial inclinations much. Legislatures continue to champion tax cuts for the rich, based on 'trickle-down economics'. But that entire concept is flatly rejected by economists. It's based entirely on one man's economic theory, and his single research paper on it is based on highly questionable standards. However, while he stands alone in defending it, he's incredibly enthusiastic about, and thus has won over a bunch of supporters who simply can't grasp why it doesn't hold up (despite the fact it's NEVER worked).
That's why, unless you're Ann Rand, it's best to leave economics out of fictional stories. If you're going to base the story on a futuristic Lehman Brothers equivalent, then base it on corruption, kickbacks and financial support, rather than on dry economic theory no one comprehends.
