First, you have to produce enough. Goods and services. Everything from food and shelter, to music and philosophy.

Second, because prosperity means widespread affluence, you have to take what you produce and get it to everyone or as many people as possible.

Third, you have to be sure you’re producing the right stuff – food that makes people healthy, philosophy that doesn’t turn people evil, housing that keeps people healthy and in good social contact with each other, and producing in a way which doesn’t destroy the bases of prosperity, whether that’s the soil, water and climate you need to grow food, or the ethics which make prosperity possible.

The principles behind this aren’t that difficult, really. Use the free market for what it’s good at (creating and distributing certain types of goods and services.) Discourage rent-seeking. Understand that how much money people get is largely unrelated to their contribution to society. Remove bottlenecks to growth. Don’t destroy your sinks (like carbon in the atmosphere), don’t overuse renewable resources, understand the obsolescence of non-renewable resources. Keep the rich poor, so they don’t buy the political system, keep influentials independent as much as possible, keep the interests of the powerful aligned with the mass of society. Don’t financialize.
