It is defnitely not hard, with vast land, America still have a big room to grow. Because the population is just 300m, and the America land occupy 1/3 of the total earth surface area, that is lavish to everyone! But why land? Is land really matter? Of course land is the only real wealth that is natural, but idk why would capitalist like to create artificial wealth such as intangible stock, paper asset, intellectual property etc, they are all clearly wealth destroyer, yet they would not stop lying over and over again. When you look again how the rest of the continent and compare it to America, we have to compete with the rest of the 2/3 real estate on the earth surface area, which is highly competitive tbh, 6.8b population having to compete with 2/3 of the existing land, while America is lucky enough they have just 300m population with a gigantic 1/3 of vast land, is it not life in easy mode?
