McDonald's is debuting a wild new sandwich

While many fast food businesses vie for power in a brutal struggle to make it to the top, there's only one that never has to worry about that problem.

That would be McDonald's  (MCD) , easily the king of the pile, thanks to sheer size and systemwide sales. It may be hard to believe, as it seems like there's a McDonald's everywhere you look, but the company is also in the midst of planning an aggressive expansion that includes 50,000 new restaurants across the globe by 2027. Supersize me, indeed.
