I really suggest listening to talk radio. I mean, if you just listen to what the talk hosts are saying, they sound like they are lunatics.

You can't get votes that way. So [the Republicans] have been compelled to mobilize a base of voters and gone to elements of the country that have always been there but were kind of marginal to the political system, for example, religious extremists.

Labor has been severely undermined, but that's happened before. In the 1920s, the labor movement was virtually crushed, in large part by Wilson's Red Scare, but it dramatically revived in the 1930s. It spearheaded the social-democratic New-Deal style changes which were beneficial to the country - not sufficient, but beneficial. That could happen again.

It’s ridiculous to talk about freedom in a society dominated by huge corporations. What kind of freedom is there inside a corporation? They’re totalitarian institutions - you take orders from above and maybe give them to people below you. There’s about as much freedom as under Stalinism.

If we move toward the weaponisation of space, we can bid farewell to the planet. The chances of survival are very slight.

Democracy, in any rational form, also imposes conditions on majority rule. That's what the Bill of Rights is about, for example.
