If you want to get rich, you need economic growth. To create economic growth, you need people to be creative, to produce things, and to bring them to market and exchange them. But producing and creating things needs investment - education, training, buying capital equipment, and so on. That's risky, because your business may not work and you could lose money. But if you have no secure rights over your own property, it's suicidal. That is why you need property rights and the rule of law.
