I don't say thing as much as I express first principles.
Fiat is created with 0 cost thus there is no risk and it's at the expense of everyone who is holding the currency without the power to create new one.
Cryptocurrencies based on POW algorithm are very costly to create and those who risk the most, those who own the most miners create the most money. Cryptocurrencies based on POS or DPOS like Steem are much less costly to create but still those who have the most to lose and to gain from the currency succeeding are those who create the most new currency but only proportional to how much they own.
Steem is a bit different. Some of the newly created currencies are allocated to authors and the creation of new tokens are delegated to the witnesses.
In POS, if someone owns 1% of the coin, they will create 1% of the new coin. No one is losing anything. Everyone is increasing their stake proportional to how much they already have.
