Start digging.
It's much worse than in the real world.
Richest 1 Percent Control 39 Percent of World's Wealth
In bitcoin, the richest 0.05% Percent Control 50 Percent of the Bitcoin's Wealth.
Good chart.
The new system is even worse then the old.
Greed is good
That is nonsense. 1 address =/= one person. MtGox cold storage addresses (and just about every other exchange, many eWallets, coinbase, etc) hold the value of thousands of individuals.
Drawing an equivelent chart for dollars would be saying.
The top 10 banks have 90% of the money supply on deposit so 10 individuals own 90% of the dollars. Obviously an asinine conclusion as the value of the deposits at a bank aren't owned by the bank and even if they were don't represent the wealth of an individual.
