I'd like to ask for thoughts on what folks here think constitutes our infrastructure, as it is mentioned a lot but not really discussed. What is infrastructure and how best to promote it? I believe that the most important function of our government is to create or facilitate the complex infrastructure that supports our society and civilized world. I've been traveling in Italy and Greece for the past couple of months and note how the great cultures of Rome and Greece became great through the infrastructure they created that made their societies dynamic. Rome became great through the development of water systems, transportation systems, creation of markets and public facilities, and civic planning, at least in my perspective. I think other great civilizations were similarly driven. In our era, our infrastructure is a key to our success as well. Communication, power, transportation, financial, and many other structural technologies are easy to see as driving the infrastructure of our age, but we seem to neglect some parts over others. As an example, I'd note that public transportation is far more available in italy than in the US, and much cheaper though is heavily subsidized. It's also utilized to a far greater degree. I've been able to travel all over Italy at a fraction of the cost of much shorter trips in the US. Mass transit is available to a wide degree and seems to be efficient and widely used. Fast trains can take you all over Italy at incredible speeds. It's pretty cool to safely travel at 180+ mph on trains that run hourly on many routes. Why is that not a good idea in the US? Our failure to see the benefit of actively promoting that kind of infrastructure will limit us in the long run, especially in the areas starved for growth. National defense isn't just about military might. I also believe there are very human infrastructure elements that have made us strong. I believe it's to everyone's benefit that our population is healthy, educated, fed, and housed. How we get there is a great subject of debate, but poverty, malnutrition, ignorance, and homelessness are a poor means to maintain the dynamic nature of our society. When we consider the need of our society to develop and maintain our infrastructure, I think it's dangerous to neglect all aspects of what that means. Our success is dependent upon how broadly we can tailor infrastructure for the majority of Americans, not only those that are the most competitive, advantaged, or who have the greatest access to the infrastructures of our coastal and urban areas. Thoughts?
