It is true. It's more true on PoS than PoW, since the mechanism in PoW is indirect. We can also consider how it works with traditional currencies, such as dollars, which has a hybrid PoS/??? system: you can receive resources by having the most resources (federal reserve deposits) and you can also receive them by performing services which the democracy deems useful (government spending), and to balance the numbers, resources are passively taken from people who spend their money but not from those who hoard it... maybe not the best design :)
