If having a national defense and an infrastructure that has enabled a person to build that kind of income

I don't understand this argument. The infrastructure benefits everyone. The opportunity to succeed from that infrastructure is available to everyone. The road that leads to the grocery store benefits the grocer and the countless consumers who use it. Who gets the better side of the bargain and how do you determine the magnitude of that inequality?

If anything, public infrastructure tends to help the little guy. Historically, when public services weren't provided, the rich paid for their own needed infrastructure, protective services, etc. Those services were geared exclusively to help the wealthy land owners. If you got protection from the watch patrolling the nearby keep, you were lucky because they weren't really there for you.
