Buffet has mentioned many times to his shareholders that Berkshire's large size is an issue. But that's not how Buffet beats the market. Berkshire is not a company that can be compared to other mutual / managed or hedge funds, and this is where Kiwi Saver funds really fall short. They simply can't 'broker deals' like Berkshire can. Good examples was when the 2008 GFC hit, no one had $ to be bailed out. When Goldman Sac wanted money, where did they go? When GE wanted money, where did they go? They knocked on Buffet's door step asking for $ and in classic style, Buffet named his terms. 10% p.a. + options or convertible warrants or preferred shares. These kinds of deals managed funds don't have the ability to do or simply, are not in the loop of things. Buffet is also famous for conveying deals that require large amounts of $. Such as Burger King moving to Canada (to buy out Tim Hortons). Kraft Foods, Mars Confectionary, 3G. When one major corporation doesn't have the funds to buy out another, they usually knock on Buffet's door.
No one really knows the performance of Berkshire after Buffet is gone. But we are assured that succession plans are already in place and in Buffet's last years, he would simply let the younger managers take place and make sure the Berkshire culture remains within. It's a lot different to how Finance companies or managed funds operate where they may cycle through many different managers to tweak things in their portfolio throughout the years.
I'm hoping my wife understands my approach to investing and why i'm hesitant to Kiwi Saver. She knows that NZ may not be our home for the long term and there may be a good possibility our children may move abroad. So being locked into Kiwi Saver until we're 65 is not something in our books.
One thing for certain, no one really knows what the future will hold.
