Can someone explain to me how (or why) the Republicans can do a better job in reviving the economy?

I've been a Democrat my entire voting life, and now that the Republicans are pretty much going to run legislation from hereinafter, I wanted someone to explain how their policies can actually be better than what we are having right now.

Maybe this will create some optimism. Maybe I'll have an open mind, after all my fellow Americans DID vote the Republicans in. And at the very least, this will let me know what to expect.

I will sincerely appreciate any and all of you who will choose to respond.
