It's about the same likelihood as expecting political and economic change in the country you live in. The parameters are the same. You have the wealthy class and you have the others. The wealthy class is the one that holds power as was always the case throughout history.

Now what makes them distribute wealth or power? The fear of system collapse and loss of their position. As long as it is perceived that their position is safe, the rules of the game don't change. When they start fearing for their position is when they start making amendments to the status quo. That doesn't mean a complete change in the structure, but usually only enough to appease the masses below them.

Why am I contrasting this to our societies? Because voting power is based on your financial worth, same as in the real world of lobbying for policies.

While we are voters on other social media platforms when it comes to liking posts, we are lobbyists on Steemit. There is no voting going on here, only lobbying.
