Found this thread after finishing Thomas Piketty his book. Would love to discuss his findings and where Bitcoin can help us.

Short summery of the book for those who didn't read it:
-rate of return on capital was during the last 200 years higher than growth, in percentage.
-if rate of return is higher than growth, capital will be more and more concentrated as long as you don't spend it, or more precise, spend less then rate of return minus growth.
-if capitial is more concentrated, the rich will be richer until a few people have all wealth, or a revolution or war starts.
-solution of Mr Piketty: progressive wealth tax: 0.1% until 200,000 euro, 1% from 200k to 1 million, 2% above 1 million.
-the bigger a persons private capital, the more affordable it becomes to hire a personal investment manager and the heigher the rate of return.
-the rich 0.1percent of society has mostly stocks, derivetives, etc, where middle class people mostly have a house as part of their capital.
-central banks should fulfill the role of lender of last resort
-gold based economy has prices which go up when large amount of new gold are discovered and down if the economy grows. Therefore, gold based economy is bad. A steady inflation is needed.

I don't think Thoma Piketty knows about bitcoin. With bitcoin you wouln't be able to rescue banks if needed. But banks wouldn't be necessary, but optional. Transactions can be done within the blockchain, but you might use a bank if you are an entrepreneur in need of money or as an individiual who wants a heigher rate with the risks that involves.

If steady inflation is really needed, it could be implemented in a cryptocurrency like blackcoin.

Any thoughts on the topic: are central banks really needed? And what can bitcoin do to help solve the problem of the rich getting richer? Is inflation really needed? And doesn't his solution with progressive wealth tax simply lower the rate a bit, thererfore just delaying the process of the rich getting richer a bit?
