You can tell it's a set-up by how they refer to the top 1% of wage-earners rather than the top 1% most wealthy families. The list of the top 1% of wage-earners is always changing because people lose their jobs or change addresses all the time, and many people hide their reported earnings in tax havens or non-profit organizations.

If they wanted to be legit, they would vociferously distance themselves from the old farts holding up anti-capitalist signs and Chinese flags. I saw one guy holding up a sign with a chi-rho (used as a symbol of Christ).
