It’s very cool that you’re looking for interactive ways to help the community understand the tradeoffs involved. I’ve done a similar activity with the faux-money, where participants could allocate however they saw fit. In this situation, it might be a good idea to have a series of short scenarios prepared, where you could explain what the world would look like with the (rough!) level of funding that was allocated to each section. What does a draconian cut in the capital budget look like? How about keeping salary funds flat? Would it include cuts? Anything you could do to help explain the implications of any allocation could go a long way. This might help with Peter’s activity, too, to explain what the world looks like without the programs below the line.
