The problem with neo-liberals is that they believe the propaganda that the govern-cement is here to help the poor. Not once have the studied all the ways that the govern-cement has made the poor worse off with every law and act they pass. The neo-liberals never realize that they cannot just pass off their the need to help to someone else and wash their moral hands of it.
As for a shit in... On the surface, it sounds like a brilliant idea. But, in reality, does it really effect anyone who would do anything?
The congress-critters would just pay more for street sanitizing in their areas, and install expensive air filters at tax payer expense. They will probably look down from capital hill at the pile of shit and thing how glorious.
So, i do not feel it will really make the statement one would want.
Unless that statement... is art.
