What a tricky situation. I personally like the idea of 1 Percent'ers mingling with the other 99% of the population more, but they need to do it in a hyper-aware, super self-critical approach or backlash (as mentioned in the article) will occur and tensions will arise. The privileged need to be aware of their privileges, especially when those privileges can be so apparent to others. High walls, exclusive bars and paid workers doesn't seem to mesh with some of the tenants of burning man.
But I really like the idea of the wealthy spending money to make a community of disparate peoples more enjoyable if it's for the entire community. That idea seems to fall in line with many of the burning man principles.
