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.
Adam Smith, Karl Marx, and John Locke are influential economists who generally agree on the importance of property rights in driving economic progress. According to Locke, an individual's labor gives them ownership over any asset they create or maintain through their own efforts.
