I was pleasantly surprised to see this notification at the top of React for Beginner’s site:
Hey! I noticed you are coming from Indonesia where this course may be a bit expensive.
I support Parity Purchasing Power — I want to make this course affordable for everyone around the world.
If you need it, use the code INDONESIALOVE for an extra 52% off the listed prices.
Parity purchasing power is something I haven’t heard before. According to The Balance:
Purchasing power parity is an economic theory that states residents of one country should be able to buy the goods and services at the same price as inhabitants of any other nation over time.
Purchasing power parity is used in many situations. The most common method is to adjust for the price differences between countries. For example, China produced $10.98 trillion in goods and services in 2015. The U.S. produced $17.95 trillion. You cannot compare the two without taking into account the fact that the cost of living in China is much lower than in the United States.
For example, a McDonald’s Big Mac costs $5.04. In China, you can get the same thing for only $2.79. People in China don’t need as much income because it costs less to live. For more fun comparisons, see The Economist’s Big Mac Index.
