Thanks for posting the link. It's a good read in the sense that I like both Gladwell and Simmons and enjoy their exchanges about pretty much anything.
However, I'm not 100% on board with everything they're suggesting. In particular, I really dislike Gladwell's use of the 22 y/o kid going to work for Goldman Sachs. I think that is a poor analogy. It's possible that race and class have something to do with certain people's reactions to Lebron, though definitely not everybody's. But there are probably much better hypothetical scenarios that could be used to convey that point so that people like me will listen better. I get dismissive when people get lazy with analogies.
