And none of it is money-related.
1. You need a bunch of people who are fundamentally honest, willing to work to get ahead, but not greedy (will not exploit others for gain).
2. You need a large "opportunity" space. What I mean is that resources must be available in the economy that are available to the working class who have inititative. In the U.S. economy, that meant available free land from the late 1700's to the late 1800's. In the 1950's, it meant available factory and management jobs as the economy grew. The money doesn't need to be there free, but it must be available to people who show initiative.
3. You need a government that rewards people who do work and show initiative, and not burden them with large tax bills. Also, the government needs to be honest enough that large corporations don't control the economy, and stifle innovation.
4. Finally, you need a work force whose wages are reasonable for the world, while their education level is relatively high.
I think it's less about how many dollars can be doled out to individuals and more about whether people are honest, and whether the government supports the creation of wealth, and lets the working middle class keep some.
