Look around. Chances are if you live in a city or suburb, there is a McDonald's somewhere near you. There are about half a million worldwide. Do you think McDonald's willtake over the world?
McDonalds doesn't have any real territorial power right now. I find it more believable to think that they could completely take over the fast food business.
If McDonalds took over the world, we'd be screwed.
If McDonald's would take over the world, people would just sit home with their fat family and watch some stupid McDonald's cartoon.
The only healthy people on earth would be the ones who work at McDonald's. The CEO and high standing people wouldn't be healthy though (fat I assume), and they would be money greedy.
Cows would be extinct and they would starts making burgers of other animals, and when all off those are extinct they would secretly turn cannibal (ewwww). And some years after that the whole Earth's eco-system would be destroyed, humans would go mad, blah blah blah bye bye humans....and Earth....
Well for awhile things would be fine for like 2 minutes than the prices would soar and we all would end up working for McDonalds and Ronald McDonald would become a symbol of terror and opression the forests of the world would be cut down for grazing the rest of the land planted for potatoes and only mining for salt until eventually the population grows so fat the earth is knocked out of orbit and plunges into the sun! Phew long sentence.
