Interesting post. It is true there are whales, and they will control a lot of the power. But you also have to realize the people gaining power will only be the people who make quality posts. They will be the one's coming up in the world. But it is similar with any crypto. If the community who created in it or has a vested interest in it want the destroy it, they usually can. But you would assume the people who have $1,000,000 in steem power probably don't want to turn small posters away, they in fact want to promote these small posters because those posters can influence a group of friends, and spread news to social media. This can then make everyone who is currently on steem richer. Also people still argue that if VISA invested all their money into bitcoin and turned it to shit, they could. They would also lose a lot of money when they sell all their bitcoins, but they could. I read a really interesting articles about how whales aren't destroying the community but instead creating opportunities, here is the link: https://steemit.com/steem/@magnebit/top-5-reasons-why-whales-posting-content-is-good-for-steem
