Economics is all about consumption. People either spend money now or they use financial instruments - like bonds, stocks and savings accounts - so they can spend more later.
Economics is sometimes associated with the study and defense of selfishness and material inequality, but it has an egalitarian and civil libertarian core that should be celebrated.

The arts community is generally dominated by liberals because if you are concerned mainly with painting or sculpture, you don't have time to study how the world works. And if you have no understanding of economics, strategy, history and politics, then naturally you would be a liberal.
Really, the proper study of economics is fulfilment, not consumption... It doesn't even matter if it's a green product or a green house... It's still consumption. What matters in this world is the fulfilment of people's needs and the fulfilment of their aspirations.
