It's a technology in the sense that the financial system has been very carefully built, over centuries, in order to not collapse, and to make transactions easy and efficient. It's easily as complicated and sophisticated as any mechanical device ever created by the human race. It basically lets us create modern society. So when the OP is flirting with arguing for tearing it down, there are three alternatives: 1) reform but stop short of tearing it down (legislation has done this several times before), 2) propose an alternative system that has a realistic way to preserve modern life, or 3) admit that you're going to destroy modern life in order to attack wealth inequality. For 3), you're going to find very few people who are willing to go along with you. For 2), if you can't convince us that your plan is realistic, we're going to assume that you really are at 3). As for 1), you're going to have to get it through Congress. It's been done, as I said, but usually after a major crisis. You probably don't have the urgency in voters' minds to drive it now, and Congress isn't great at passing anything right now. (Am I the only one that thinks that "can't pass a budget, which is the basic job" should mean "fire them all"?)
