Is it in the interest of high-income countries to promote the development of poor countries? Why or why not?

Answer 1

Yes. If low-income countries are developed, they have the money to buy our exports.

Answer 2

But why is it worth investing in a place, if you don't know if they will be valuable to you in the future?

Answer 3

All investments are gambles. The odds are that the investments will pay off.

Add that to what's right from a humanitarian point of view, then it's usually a win-win situation.
