Why are we "reforming" healthcare? Pt. 2

This is an honest question for most right-wing supporters of repealing Obamacare: What are the substantive, objective, measurable goals you hope to achieve?

When  Obamacare was being debated (for more than a year), any supporter thereof was able to say what the goal was: universal coverage and slowing the growth in the cost.

What is the goal now? What end does Sen. Todd Young, Rep. Susan Brooks, Rep. Todd Rokita (he with the wife earning $20,000/month from the Town of Fishers), or Rep. Trey Hollingsworth (R-TN IN) hope to achieve?

If we get a substantive answer to that question, we can then determine whether Rs and Ds actually share a common goal. I suspect they don't.
