Well, I'd respond in kind. People have the deeply in-built assumption that we can simply solve all our problems by giving all the power to the thing that fits in the "tribal leader" slot in our instincts.

But we've given our "tribal leader" (government) more power than any single entity has ever had in history, and our problems are getting worse, not better. If you prefer a less binary argument, if giving more power to the government is going to improve the problem of inequality, inequality already ought to be getting better, not worse. If inequality is getting worse, and we've been giving more and more power to our government for decades, it seems irrational to conclude that the only way to "fix" inequality is to keep giving the government more power.
