Here was a great article (as in informative and well researched) by a liberal author about global rescue.
The Tricky Ethics of the Lucrative Disaster Rescue Business

I'll give you the synopsis of the article if you're not into reading it entirely. Shame on you customers of global rescue who were rescued promptly from Nepal after the 8.0 magnitude earthquake. Shame on you that Global Rescue was so well entrenched locally that they knew who to call that had a helicopter. Shame on you that global rescue could persuade pilots between mandatory government controlled shifts of relief efforts to pick up global rescue clients in crisis. Shame on you global rescue clients for getting rescued when there was a person that didn't pay for global rescue that was dying at a triage unit of a hospital because he couldn't get a helicopter flight out and you did. It isn't fair that people that bought a special rescue service get rescued by global rescue and people who do not pay for such services don't get rescued.
If you can get over the shame, shame, shame, capitalism is evil and this product proves it because you get preferential treatment bit, here is the honest conclusion of the wired article: Global Rescue works if you pay for it and it may even work at the expense of others who did not pay and therefore did not get urgent services. It even worked in Nepal when the government took martial law control over all the civilian helicopters during the earthquake crisis because global rescue was so cunning they could get pilots to work between government mandated flights to get their customers to safety.
I personally can live with that moral conundrum because I'm paying for preferential treatment in the same way I pay for preferential treatment in my healthcare decisions. To others that would be anathema.
