Argument: Dems focus on regulating businesses, protecting consumers
"Democrats vs. Republicans: What DO they believe?." OnTheIssues. 2000: "A liberal would say that a proper role for government is to regulate and oversee the economy. Liberals say it's proper for government to ensure that companies do the right thing (such as pay minimum wages), and to ensure that people act responsibly in their finances (such as requiring contributions to retirement savings)."
Cody Hodge. "Democrat vs Republican." Helium: "Democrats believe in the regulation of businesses, and that people need to be protected from abuse by industries that otherwise would have the power to run free over the American consumer."
