Bitcoin is not a democracy (have you not even read Satoshi's paper?).
Satoshi said 1 vote per CPU (not 1 vote per person) so surely you can understand that one person can have more than one CPU?
Yes, in this sense it is not a democracy... maybe a technocrazy... cpu's are voting...

So at the end the wealthy has more power. Was inevitable. But still it is some kind of decision finding. And the strongest wins because he can.
