I think David Cameron has said that no government manager should be paid more than x times the average wage. Something like that is tangible and if the protesters said that they would like to see a cap on CEO salaries (which are far higher relatively than they were two decades ago), I think they would have a lot of people agree with them. Or advocate for the phasing out of negative gearing on investment properties. I'm not saying they are the best policies (I haven't spent enough time weighing those up) - just examples of what I'd like to see from them - simple, tangible ideas.
