In earlier days, normally, the trade was a family business. People used to stick to their family trade, irrespective of the profitability. They were respecting what their ancestors did. A carpenter’s son used to become a carpenter and a soldier’s son used to become a soldier. The community was recognised by the trade they did, and it was even used as surname. People were not entering in the trade of others, and an act of doing other’s trade was even punishable. There was no competition as the productions were less and the demand was certain.
