The economic system is created by people. The economy is not how it is because of an act of God or because of some natural state of affairs beyond our control. The political process has delivered an economic system designed by the already wealthy and the already politically powerful to maintain the wealth and power of those who already have it. Real democratic activity is rare.
For that reason the economy is constantly running in sub-optimal mode, with the brakes on. Taxation policy favours the wealthy, the greatest subsidies are paid to friends of the government, and insider knowledge is used to promote the best interests of political supporters. In economic terms, the market is distorted by insider influence. There is no level playing field, and the world isn't flat.
In a modern market economy there is a promise of equal opportunity for all, but the promise is false. If you get an education and you develop useful skills, you might expect to find a place in the economy where you can be both productive and useful. Be the "best you can be" and live up to the highest ideals. This is good advice, but it's not a guarantee or a promise of financial success.
Abundant "wealth" as a promise is currently being marketed as "The Secret", or "The Law of Attraction". Those's are old myths, based on half truths, compounded by lies. Our willingness to follow such false trails obstructs our real progress. We could do better.
The laws of Economics are bitter and tough, but useful. There is no "free lunch" and everything has a price, a cost and an opportunity cost. We try to avoid or pass off real costs, and we don't understand "opportunity cost" very well.
