I think that was needed to make his point(IOW it was related). It is akin to the assertion that we need to spend more money on "Art" and "education". The education system is the epitome of the "spend the people's money" approach. If you spend money and the spending achieves your goal, spend more money for even more benefits. If you spend money and the results are not achieved, spend even more money to fix the "problem".
We argue about how to do this, what to spend it on. For example, gov't is encouraging consumers to buy homes, encouraging it as much as they can. It might seem like we are each choosing how to spend our personal funds if we don't understand the purpose of money.
