With very low interest rates, and ridiculous Fed policies (QE) designed to 'reinvigorate the economy', but which really just pumped tons of extra cash into stocks and bonds (i.e. mostly the 1%, and institutional holders like pension funds) - you have tons of liquidity chasing value creation.
It'd rather seem that 'the power' is now in the hands of those who can create value.
Or more cynically: money goes to those who can convince others that value is being created so they can 'collect money' for their product/service.
There's nothing inherently wrong with this situation, it just means VC's are getting squeezed, and their 'amazing skill' of being able to 'spot the best opportunities' might be being commoditized a little bit.
The 'risk' really is a sudden change one way or the other, i.e. fed-rate change, china-flop, tump-risk or just some general fear based panic causing a bubble burst.
