You can't try to sell people on all the problems all at once, because it's simply too much to process.
I think this is just a great demonstration of the differences in strength between progressive movements and entrenched powers/ideologies. The former can effortlessly blow away any supporting point ever made by the latter, but eyes will glaze over in the vast majority of casual observers in the time it takes to do so.
The problem is progressivism most often relies on that level of sophistication, and it's hard to imagine giving that up without undermining itself. Yeah, you can rally a little more support from average people by dumbing down the message, but then what gets attention is the dumbed down message, not the real important one. In your case, we might end up with CEOs putting more effort into hiding their real wealth and maybe some actual legislation regarding their incomes... but then it would be done, because the majority of people who were attached to that dumbed down slogan would say "Ok. We did it." Majority of problems would continue.
In my opinion, which may sound a little unprofessional from a PR standpoint and definitely unrealistic, people simply NEED to pull their heads out of their asses and do some real thinking. I don't see how we can get anywhere otherwise. Society is a product of its culture, and if the majority of the population is getting ass-pulled by whatever political slogan makes them feel the best about themselves, then we're going to get a society proportionate to that level of stupidity no matter what those slogans are.
I just happened to be in high school government class during the 2000 elections, and I'll never forget my teacher asking everyone of voting age in the class who they were going to vote for and why. At least 1/3 of those questioned said they were going to vote for Bush, because he seemed like a regular guy that they would share a drink with at a bar. This blew my mind. I could not believe that people would consider this as a leadership quality. This was seriously one of the biggest WTF moments of my life. Unfortunately, I've grown to accept that a significant portion of people are like this, and I don't think we need to dumb ourselves down to their level to get them on our side... I think we need to motivate them to actually give a shit. That may not be realistic, but I think it's necessary.
Edit: I also think it's happening, even if small-scale. I'm seeing lots of signs of a cultural shift online, in the protests, and in people I know face-to-face. I've been sharing lots of information with people lately who are actually listening, questioning, and valuing my input, when just months ago they would have been rolling their eyes at me.
