Actually that statement suggests to me that he has a very real understanding of at least some of the problem. Show me a series in midget racing right now that is thriving running 1/2 mile racetracks. Powri is doing well by sticking with 1/4 mile and under (even 1/8 mile) tracks (barring Angell Park, which consistently has lower car counts than Powri averages). The largest race of the year is held at a track that is smaller than any track on the USAC schedule (Chili Bowl).

You needn't look much further than Indiana Midget Week where Lawrenceburg (the biggest racetrack) had the lowest car count of the week. While there are certainly other variables, it's hard to argue that size of the racetracks DOES have a significant impact on car count.
