The GOP doesn't care about the end result unless it is them holding onto all the power and wealth in this country.
I don't think they even necessarily care about themselves having the power. They're fully beholden to the financial interests of the wealthy now, so they have no choice. They're replaceable if they don't play ball, and furthermore, they handed them the leverage against the American people, so they've fucked us both ways (every which way actually). Now they're just trying to maintain the status quo that they created because if they don't their scam will come crashing down. And they'll be the ones held responsible (rightfully so).
What's more concerning is that our debt is now larger than our GDP and growing. I could at least understand if your economy is growing as fast or a little faster than your debt in that your income would grow fast enough to pay for it all but in this case, we're taking a pay cut with no guarantee that the economy is going to benefit.
T-Rump and the GOP say that the economy is stuck and needs a push and yet the Fed is building a case that the economy is too hot and needs a rate hike (or 2) to slow it down.
I guess as long as the share holder class get the most, there won't be much to worry about on the economy overheating....maybe Wall Street but definitely not Main Street. The 'trickle' will never make it down below the penthouse.
I'm not sure that the trickle will even make it into the US, as even if they got all the changes they want, there's still so much room for them to end up better off hiding the money, and a lot of that money is gone for good as there's no benefit to them revealing it anywhere close to fully. So they'll probably make a big show of bringing some meager amount back to make it seem like they're operating in good faith. Republicans get to claim it was them, and they both hope the American people will be none the wiser. If more of it gets revealed, they'll just say they held out because of "uncertainty" with the tax reform or whatever they can come up with, and then let the political system play the blame game and usual garbage to obfuscate things ensuring that nothing meaningful will be done about it.
