PoS Ethereum with ETH native yield is the most democratized consensus mechanism as it offers the same proportional return as 32, 320, 3200 or 32,000 ETH.
They will all receive the same yield of around 5%.
This is in stark contrast to PoW miners due to the economies of scale that PoW hardware and energy costs can bring.
A $100 million investment in a mining facility would generate well over 10 times more computing power than a $10 million investment.
