Why has the GOP done so little to help average working people?

Hartmann Report -  Gallup just found that only 10% of Americans approve of the job Republicans in Congress are doing, with 86% actively disapproving of the GOP’s behavior.  Turns out, there’s a reason........

Since 1981 Democrats have passed the Family and Medical Leave Act; Earned Income Tax Credit expansions; Children’s Health Insurance Program; Affordable Care Act; Dodd–Frank Wall Street Reform and Consumer Protection Act; American Recovery and Reinvestment Act; Every Student Succeeds Act; American Rescue Plan Act; Infrastructure Investment and Jobs Act; Inflation Reduction Act; PACT Act, and dozens of others.

Which raises the question: Why have Republicans avoided doing anything at all to help average working people for over 40 years?
