Only for the largest account holders, whom statistically will receive most of the newly generated money (and even more as they continue to accumulate newly printed PoS tokens).
PoW distributes block rewards proportionally to hash power and these proceeds can be used to buy more hash power to achieve a compounding effect. From what I understand all of the viable PoS systems offer a fixed rate of return on the stake. This is like PoW forcing everybody to use the exact same hardware; a benefit to the little guy at the expense of the large account holders.
