The average citizen is more principled and less prone to corruption than the average modern politician. I don't think it would be a problem if politicians ended up more naive as a result. Just having well-meaning politicians would be a significant step up.
That said, I think we should rely less on government intervention in the economy. We need to fix the monetary system to provide a level playing field, then once that's done, we need to trim back regulations. The way to solve the corporate monopolization problem is through increased competition. The government's primary role should be to promote maximum decentralization.
The government should not concern itself with equality of outcomes; it should only concern itself with equality of opportunities. It should not think about efficiency; it should trust the free market to take care of that.
