Starting a business is easy. I've personally done it in the early 2000s, and it's easier today. However, it's structured for traditional businesses which produce returns relatively early.

It is not structured to support "startup"-type companies like those in the US. Yes, Silicon Valley is the focus on HN, but the range of options beyond what you find in the UK is available in many more places than just SV.

In the UK and Europe you can potentially find an angel investor. Once you go to the next levels of finance then it gets tougher. In the US, you have access to the next level of VC finance which comes from a relatively large pool. Most financiers in Europe tend to be conservative, although there are efforts to change that. Hence, companies flipping to being US-based.
