" Good economic institutions will encourage citizens to invest, accumulate, and develop new technologies, as a result of which society will prosper. Bad economic institutions will have the opposite effects. One problem is that rulers, who have the power to shape economic institutions, do not necessarily find it in their interest to allow their citizens to thrive and prosper. They may personally be better off with an economy that imposes lots of restrictions on who can do what (that they selectively relax to their advantage), and weakening competition may actually help them stay in power. This is why political institutions matter - they exist to prevent leaders from organizing the economy for their private benefit. When they work well, political institutions put enough constraints on rulers to ensure that they cannot deviate too far from the public interest. "
