Well I don't think the whole system has to be broken down and rebuilt from scratch. There are lots of pretty basic ideas floating around for getting money out of politics.
Once you can employ people to work for your political ends (by directly engaging with congressional staff, by producing supportive research, by working a PR campaign...), you have a bigger voice than someone else, whether laws allow you funnel campaign cash by the shipping container or not.
My guess is that the only real way to balance this out is have more citizens talking to congressional staff.
