You’ve revealed their soft underbelly. The first wave will confiscate and destroy all Twinkies.
No revolution starts until the middle class is radicalized. It wasn't the students who started the Iranian Revolution and brought Ayatollah to power, it was the shopkeepers who decided to join them. Just as you suggest -- jokingly, I'm sure -- no revolution would start here as long as we had our "twinkies". But the day the supermarkets close, because of a credit crisis, or whatever it may be, the day our normal comforts are denied us, that's when you'll see our social structure come unglued. We are so complacent, we no longer have any tolerance for that. The parasitic classes, those who depend most on entitlements would riot and take what they wanted by force, like they do in urban riots, only nation-wide. Then you would see a revolution, more like a merciless counter-revolution, as what had been the middle class became radicalized and struck back, real hard. Only, it wouldn't stop there.
