Boy, that's a tough one. What are you calling LT? You may have noticed that as a society advances it does so at an ever faster rate. That means the rules and the playing field keep changing ever more quickly. Maybe "some" of the "towel heads" would like to, but there ain't no going back. Just as a guess about the only way to would be to blow things up and break them, but that only works if the knowledge is also lost, otherwise it is quickly and easily rebuilt better than ever like Japan. Possibly another way is if you run out of resources.
Maybe IP companies since they own the communications and communication being the most valuable thing. Of course you might want to ask Zeev about that since he is in the business of breaking other companies IP. Staying in the communication field you have movies and music, but they rely too much on the next big hit.
Possibly health care providers. If you have a broken leg here, it's kind of hard for a doctor in India to do anything about it. Of course the scientist are working to solve that "problem" through remote robotics. And of cousre unless they can keep raising their rates, labor costs could become a problem for them since there currently is suppose to be a doctor and nursing shortage.
Being a daytrader it's not something I've given much thought.
