If there is one thing to learn from Ray Kroc it is to always have persistence. That man never gave up and never took No for an answer. He had spent many years trying to sell new products and ideas to people and restaurants but never really got anywhere. He never became anything he wanted... until he found McDonalds, and I guess you could say until McDonalds found Kroc. To have persistence, you need a firm continuance course of action no matter the challenges you may come across.
From getting the door slammed in his face after trying to sell milkshake machines to going through divorce, Kroc overcame everything and continued to follow his plans and ideas despite how others felt. His persistence led him to a world of success, but left his partners in the dust to lay. The movie showed how Kroc found every way around his contract with the original founders of McDonalds to get his way.
McDonalds was specifically created to bring families together and get their food at a faster pace. It is an environment that is designed for customer satisfaction. This idea of a family friendly franchise blew up and all of America fell in love. Although Kroc takes credit for McDonalds's expansion, we cannot forget Mac and Dick McDonald. These two brothers are the only reason this restaurant even exists. Without them, Ray most likely would have spent the rest of his life chasing worthless opportunities that got him nowhere.
Kroc constantly found ways to innovate McDonalds. If he was told no, he would find another way to go back and get a yes. This impacted society positively because it continued to grow McDonalds into an environment that people in the 1950's didn't know they needed. The McDonald brothers designed the "speedy system" for satisfaction, eliminated the drive in feature for rebellious teens and trouble makers to stop hanging around in, and found the perfect equation to bring their own harmony into America.
Of course this was a fantastic idea the brothers had, and of course Kroc had to have it for himself. He portrayed this idea to the brothers that he was going to help them share their love of McDonalds with the rest of America, but really he was going out of his way to find loop holes and make the business his. This affected the brothers negatively as they put everything that had into their business when they grew up with nothing. All of the stress that Dick and Mac were dealing with having to work with Kroc actually ended up putting Mac in the hospital, and ultimately led to Kroc buying them out. Every decision that Kroc made impacted society both positively and negatively. He put his own partners out of business, but he built several McDonalds all over the nation to serve people. The movie reflects a lot on creative destruction in The Seen, The Unseen, and The Unrealized by Per Bylund. Kroc took this local fast food restaurant and completely rebuilt its meaning in a disruptive manner.
