What is one reason that thomas paine brings up the opposing argument that the colonial colonies have done well under British control

based on the description given, i would say it is to build ethos

Thomas Paine claims that although America has for a time thrived under British rule, it has evolved and does not require the British monarchy any longer because the British monarchy only cares about Britain, and not about the Colonies. He adds that the colonists would be the one to die in wars against the French and the Spanish, and not the British.
