Basically, the Right is the party of the economic elites, whether they are the corporate elite or a land-owning elite. Because elites are by definition a minority, they traditionally ally themselves with religious conservatives and nationalists.
The Left traditionally is the party of the non-elite -- working people and small farmers -- groups that historically and in most of the world are a majority.
The middle classes are divided in their allegiances, shifting back and forth.
The story gets more complicated in the US and other industrialized countries, where working people and the middle classes were able to acquire more political and economic power than they had ever had before. I think there were three main factors behind their success:
- 1) Fossil fuels put vast amounts of energy at the disposal of society. As Heinberg and others point out, through fossil fuels we have the equivalent of several hundred "energy slaves" working for each of us.
2) The countries that were first to industrialize augmented their wealth through colonies and imperialism.
3) Economic benefits came as a result of political struggles by the Left (think unions and the New Deal). After World War II, the elites made many concessions to working people, in large part to keep them from turning to Communism.
What distorts most discussion about the Left is the idea that the Left is the same as Marxist-Leninism ("Communism"), as exemplified by the USSR. In fact, the Left is a diverse and contentious spectrum of parties, ideas and tendencies, ranging from free-spritied anarchists, to libertarian socialists, to hardcore Leninists, to conservative social-democrats.
Even though the Left is disorganized and beaten down in the US and other industrialized countries, I wouldn't count it out. Consider:
- * After Peak Oil, the material standard of living will drop, causing popular discontent.
* After PO, it will be more expensive to transport goods and employ labor-saving machinery; manufacturers will be more dependent on labor.
* It is more difficult to gain wealth as an imperialist power. US military might is expensive to maintain, and depends on loans from Japan, China, etc..
* The lead in technology enjoyed by the US and Europe has shrunk.
* Bush and the neo-cons have made the US very unpopular in the rest of the world. They have discredited capitalism to an extent undreamed of by the Left.
* As memories of Marxist-Leninism begin to fade, other more viable forms of Leftism will have a chance to emerge.
