It is not so much the visa issues - it is the time and hassle of going through immigration and customs to never actually really enter the USA. I have waited in line at Miami for over two hours in the past and waits of about an hour are quite common place.
I think whatever money folks are inclined to spend on improving transit might be better spent than on sterile transit. Specifically, the following two areas could use improvement:
1) Immigration. The government and airports together could focus both on hiring additional immigration agents (MIA is doing this with local money) and with expanding the use of global entry and passport kiosks, perhaps to folks who are from visa waiver countries or hold multi-entry US visas. The US is already doing a pretty good job with slow but steady expansion of visa waiver, and this is also a good thing.
2) Customs. ITI at every station with a large number of "in transit" passengers would be an enormous improvement.
If immigration gets to the point where it's consistently a 5 or 10 minute wait for most passengers and customs is a breeze through due to ITI, I don't think facilities will be a significant impediment to transiting the States.
