What trade makes the most money in America?

Could you elaborate on the factors that determine which trade generates the highest income in the United States? Is it solely based on the profit margins of individual businesses within a particular industry, or does it also take into account the overall employment rates, salaries, and benefits offered within that trade? Additionally, how do trends in technology and globalization impact the profitability of different trades, and which ones seem to be most resilient or adaptable in the face of these changes?
