Yes, govt made the highways. Did not really repair them afterwards (at least around here) but it was definitely a good thing.
However, when judging by the bottom line, the number of good products created by govts is incredibly small compared to the amazing breadth and diversity coming from the open markets.
That logically makes me trust the market system overall and to prefer a small, limited government role.
But I am afraid we are moving into quite the opposite direction...
