True. I think that if Buffett wanted to address this problem his best option would be to fund an entity that could lobby on this issue and match dollar-for-dollar pharmaceutical company donations for house reps and senators that were willing to push to reduce the cost of healthcare.

Tackling healthcare is one 'big issue' that could have a huge effect on the US economy and living standards. Seems a worthy 'legacy' project for Buffett to finance.
