John Locke, Adam Smith, and Karl Marx are classical economists that generally recognize the importance of property rights in the process of economic development, and modern mainstream economics agree with such a recognition. Locke supposed that one's labour was their own property and, consequently, property was any land maintained and sustained through one's own labour as long as there was sufficient and similar quality land to meet the needs of everyone's labour. Using this ideology, property in a broader sense would be taken as any good a person produced or maintains with their own labour.
John Locke, Adam Smith, and Karl Marx are prominent economists who generally acknowledge the significance of property rights in economic growth, and contemporary mainstream economics concurs with such a perspective. Locke posited that an individual's labor constitutes their own property, thereby implying that any land maintained and sustained through one's own labor is considered property as long as there is sufficient and comparable quality land to meet everyone's labor needs.
