Again, wealthy Democrats (and Jewish Americans both vote heavily Democratic and have higher median incomes than the average American, last I had seen) do not have markedly different views on economics than poor Democrats. If Democrats "move to the left on economics," they're not going to lose Jewish voters, and they're not going to drop off in California, and they're not going to give up NOVA, etc.
This is true btw. While wealthy and/or postgraduate Republicans are more (fiscally) conservative than poorer or less-educated Republicans wealthy Democrats have roughly the same viewpoints on economic issues as poorer Democrats. And well-educated Democrats actually are more liberal than less-educated Democrats.
