What makes a country developed?

Well, a country that has clean water available for their disposal, a steady supply of food, shelter, and clothes supplied. Businesses open and supplied almost all of the time. Cars, modes of transportation other than by foot. When you think of parts of Africa or some third world countries, they're typically the ones you'd think of as undeveloped. Countries like the U.S., England, most parts of Europe and such. Developed countries. See what I'm saying? I hope this helped.
