One of the more controversial mayors of NYC, Bloomberg is also the majority share holder of Bloomberg L.P., a major international financial information company. Despite having more than 30 billion in personal wealth, Bloomberg reckons that you should keep the cash you woud spend on things you might not use, and only use what works for you. Example? He is said to have only two pairs of work shoes over the past ten years. Clearly he could afford as many pairs of shoes as he wanted, but he only wants two - so why have more?
