The reason to invest in infrastructure is that's what makes our economy grow. When you can't get goods and services across the city because the roads are congested or the roads are in need of repair, that hurts the economy. When you are in communities that can't rely on their water systems or on their storm water systems, that hurts the economy.
The fact is, to have the economy grow, which in fact creates jobs, you have to have a good solid infrastructure. It's the backbone of what makes this country work. That's why it's so important.
