Solution:
Democracies are more prosperous than others is not a good argument in favour of democracy.Democracy is where people participate in the formation of the government. It improves the quality of decision-making. When the citizens participate in the elections, the government formed truly becomes a representative of the people. Their leaders are representatives of the people. Democracy ensures freedom and equality in the country. The governments in a democracy are more accountable and are better at resolving conflicts. But there is no compelling proof that democracy ensures prosperity, although it works in favour of the public interest.
