Chart showing difference in economic classes and speed of adoption

Two charts that tell interesting stories.

The first is a fascinating look at how money is spent by different wealth classes. For instance, the lowest 20% spends about a third of the top 20% on food, but about a fifth on entertainment etc.

The second chart is shows how much faster new technologies have been adopted recently. (look for steeper lines).

Thanks to SimoleonSense for pointing this out (probably my favorite blogger) and the people at ThinkorSwim for making it available. (BTW as an aside, ThinkorSwim has a very high number of SBU grads working there! Great place.
