The game has always been designed to favor big investors in the game and even that cant get right.

Indeed. How come you didn't know? :)
I agree it's frustrating for smaller users (I'm running 8 accounts actually, only four of those are my own) but in the end it's like everywhere: you're free to make your decisions and design the game for you the way you want it and can afford playing it (I refer to time and invest).
Yes there's users investing a lot. But you can be successful as a small account still.

P.S.: I'm not about to destroy any planets of my accounts, I still need their output to grow ... :)
