Question for Buffett and Munger Berkshire Hathaway Annual Shareholder meeting 2016

My name is John Brenninkmeijer, I am from Holland. Sam Walton used to say: THINK SMALL, he proposed breaking up Walmart if it ever hit $100 billion in sales. Some people have proposed breaking up Berkshire, but are there other solutions? For example could Berkshire invest in small cap stocks using the students from Columbia who are here today as unpaid interns? Or use simple stock screens to invest as Benjamin Graham proposed in his last interview? What is, in your opinion, the best way to overcome DISeconomies of scale?
