A lot of comparisons are being made between these two movements.  And if one were to watch the media, it certainly looks like the fault lines are drawn, i.e.,:

Tea Party = loved by Fox News = conservative
Occupy Wall Street = treated with disdain by Fox News = liberal 

But some are noting that the OSW movement really isn't hippies in a drum circle with union guys giving speeches.  It seems to hae drawn libertarians as well.

But why?

Here's why:

What’s wrong's with the country?  The unity of government and corporate power against people’s freedom and prosperity.

That's a message that both movements can rally behind.
