The issue I have with the situation here is that, as many have pointed out these folks have the means to literally board a private aircraft and go anywhere on the PLANET for the absolute BEST help available.
Is it though? I've had some of the worst experiences with private doctors at some "recognised" clinics, whereas the state service and "free" services I have received are beyond anything money could have bought me.
Private clinics just want to draw as much money out of you and your insurance as possible.
My personal view is the health system in the US is the worst in the world. (I'm not saying the doctors are bad, I'm saying the health system is bad), but in the rest of the world where universal health care is available, you can obtain some of the best treatments available without the fear your doctor is just trying to make as much money is possible, so they care for your health.
Bottom line. Money is meaningless, so board all the private jets you like. It'll make no difference.
