"On the one side, there were the economic conservatives. These were people that anybody following contemporary Republican politics would be familiar with. They spent a lot of time worrying about the way government intrudes upon economic liberty. They upheld freedom as their highest political value. They admired risk-takers. They worried that excessive government would create a sclerotic nation with a dependent populace" ("The Conservative Mind", David Brooks, 2012).
