It's generally hard to have an impact when your movement is generally devoid of a point or solutions.
I wouldn't say it's falling on deaf ears. People are saying "I'm angry".
However, that's about all there saying.
That's why over 60% of the country is now against occupy Wall street.
If they actually focused on real issues and the real problem, they'd have more support.
Like say... "If the banks were too big to fail, why didn't the government, as a precondition for loaning banks money, require in that accepting that money, they would then be split up into smaller banks that wouldn't be too big to fail."
Instead the whole movement seems to be characterized as "Booooo! Rich people suck!"
