The USA for 2020 was the most powerful state with the highest GDP. The country owes its power to the "three whales" on which its economy is based: the free market, freedom of speech, and its constitution. Free enterprise, the capitalist system based on private property, the natural drive to increase capital and profit, is consistent with the biological nature of Homo Sapiens. The biological instincts laid down by the evolutionary nature of our species: food, reproduction, dominance - correspond to the economic system of capitalism. Freedom of speech without which justice for all is impossible, and the country's constitution, which since 1787 has maintained the created system of checks and balances. Unfortunately, the time has shown that this system is not perfect either. But more on that later.
