Listen, each leader of the world.
What do you think about poor people of your country?
If you say no problem, your country will be very serious.
Each leader of the world must take care of,
"Clothes Foods Houses of poor people."
Some leaders may say,
"I can't do such a thing."
If you know the real economics,
You had better take care of those things.
Finally, "Clothes, Foods, Houses of poor people." will make many new industries.
Economic growth will be bigger and bigger.
If each leader of the world want to keep the power of your country,
you had better take care of poor people of your country.
At first each leader of the world must know what economics is.
