Can countries grow richer by exporting people, not goods?

The southern Indian state of Kerala has achieved prosperity not through exporting goods, but by exporting people, with many of its residents working abroad and sending back remittances. This unique approach to economic growth has allowed Kerala to thrive, despite not having significant oil reserves or major industries. The state's prosperity is heavily reliant on the money sent back by its citizens working in other countries, particularly in the oil-rich Middle East.
