In other businesses and sectors of the economy there are no such opportunities as in trading. Earnings there are always limited. A good restaurant can bring in an average of 2-3% of its turnover of $1 million per month. There is no particular point in making a restaurant more expensive in the regions, so business is limited. In trading, you can make transactions worth millions and billions of dollars, accompanied by any risks. Naturally, the higher the risk, the greater the profit and vice versa.
