To be clear it was a verbal, not physical altercation! It happened several years ago as I was having drinks with some friends. They had just graduated from university and were earning very decent money in their chosen professions.
After being students for so long naturally they were talking about all the things they could spend their money on. At this stage I had already been working for around 4 years because I chose not to go to university and had a bit of a different perspective.
In 2007 one of the wealthiest people on the planet, Warren Buffet, made a bet with a private investment company that a passive index fund would outperform a professionally managed portfolio of investments.
