> we may invest [...] too little in infrastructure, education ... It sounds like a nice-to-have-thing but how on earth does that actually follow? The US spends enormous sums on education, the 2nd most of any country on earth (behind Norway) and ~33% more than OECD average. How can you be sure the problem is that we are investing too little? Investment hardly seems like the issue, ROI seems a lot more pertinent. For infrastructure, even heavily unionized countries can build public works projects like subways at far less cost than the USA. So its hard to buy that we invest too little per se. We get very little for our investments, whatever they are, which makes people in-my-opinion rightly cautious about investing more until some honest root cause analysis of the poor ROI is performed and openly acknowledged.
