It's not entirely obvious what you are talking about from the sentence alone. I.e. whether you mean 'the economy' or some kind of system, in a computer game or suchlike.
If it's the economy, something like this is better:
- Proper management of the economy can level the playing field.
- When the economy is managed correctly, the system is more balanced and more people will/can succeed.
- Managing the economy in the correct way will lead to a greater distribution of wealth and increased prosperity for all.
If you are talking about some kind of in-game system:
- Proper management of the in-game economy can lead to greater success and a more balanced game.
