Actually most developed Democracies have economies that are relatively decoupled from their governments and their politics. Corporations operate relatively autonomously, and it is corporations which fuel the explosive growth we observe.

On the other hand, developing countries often have bloated bureaucracies and corrupt governments that are heavily involved in the private sector and corporate activity.

The difficulties I mentioned in my original post are those in which the Government is heavily involved. Corporate investment in properly functioning nations are free from (public) political hindrances.
