All of these GOPers are against government. They want to take our country back to the days before the New Deal--which they all hate--which lifted Americans out of poverty, especially the elderly that since then they have a safety net. Same with other basic and absolutely necessary goods and services we need to be an advanced country with a decent quality of life.
The problem with addressing the conservatives' arguments requires answers longer than bumper stickers. It requires some knowledge of American history. It requires an understanding of what a developed country is, and how the successful democracies have made life quality better. They have done almost the everything in the opposite of what our conservatives are advocating. If, as they say, progressive policies, which include a strong social safety net, is a recipe for disaster, why so may other countries have done so much better than the US in meaningful (and measurable) variables regarding the quality of life?
The GOP has been captured by people who keep repeating adages about how the absence of government, regulation & oversight, no consumer protection, no universal health care, no publicly-funded education, a super military (read: unlimited spending), a morality (theocratic) police, segregation, obsolete gender roles, etc, are what we need! They have no positive proposal for using our government for making our lives better. Republicans hate the government when it provides social services and all sorts of benefits to the people. It's incredible that whatever they're proposing today, we've already tried it in the past.... and didn't work very well.
But, those clowns on the stage tonight are earning kudos points from an ignorant political base who like bumper sticker messages. Oh, yeah, "Make America Great Again"..... When was America (I assume it means the U.S.A.) great again, Mr. Trump, and please define greatness... Oyvey.
