The real economy directly creates wealth, and manufacturing and agricultural production are both typical real economies. Speculative futures, stocks, bonds and other virtual economies, in essence, have not increased the goods and wealth of the whole society, which is very risky. Young entrepreneurs are often inexperienced, incompetent and lack of funds. If they engage in the real economy, they will create a little real wealth. If they rush into the market to speculate in futures, where can they compete with financial predators? It is bound to lose money or even lose everything. Therefore, we should start from the real economy, accumulate strength and experience, and wait until our wings are full, and then go to the game capital market.
