I don't think that's a very good analogy, but I'll bite. The economy doesn't really need David to have a good shot at defeating Goliath. It does need David and Goliath to compete on the same field, with the same rules, and for Goliath to not do things like corner the market on rocks. Of course, a pure market economy doesn't really have any rules like that, it's just that it can get pretty nasty if we don't have them (not to mention basic rules like 'no using babies as ammunition' and 'you're allowed to have an army, but you have to feed them'). We discovered this during the industrial revolution, and the modern liberal democracy and ideas around fair play, consumer protection, competition as an important mechanism in a market economy, etc. grew out of what we learned. Unfortunately, for some bizarre reason, we seem to be systematically dismantling most of those protections, despite knowing exactly what's going to happen. (Hint: it rhymes with 'huge, uncontrollable corporate behemoths owning all the means of production, channels of communication, and legislative agendas'). Of course, every generation seems to have its insane economic ideas. My great-grandparents had Communism. We have whatever you call the squirming progeny of identity politics brutally inseminated by Reaganomics.
