Yes, you don't "give away" your plans to the public because then they may be able to use the democratic process to do something about it, you keep it secret so that you can manipulate the media over a short period and swing through your sweeping changes.

The thing is that is completely anti-democratic. If it hurts democracy to do the best thing for a small capitalist overclass then democratic nations should be choosing to uphold democracy. I wonder if there are any such nations?
