Which country current in entire world where the ideas Republicans advocate have been proven to work?

[How would I know]

Pretty easy answer, just look at the United States over the last couple decades.

In 2007 Democrats took full control of Congress and began implementing their objective of absolute government control over every aspect of our lives. And we all know what the end result of liberal ideology they brought has been.. job losses, poverty and misery. Before that, while Republicans were still in control, the American people were wealthier, happier and more free.
