I doubt the timid and uber-wealthy people in Congress (the very establishment) will help here...and if they do, it will be very slow going as well. Look at what is happening to tax reform and the Obamacare repeal right now.
It is nearly impossible to reform a system from within a system...unless you do so over generations. The system itself fights you and your wins a exceedingly incremental, taking decades to bear fruit. You can only reform systems from the outside...so it becomes either a consistent generational campaign (such as the Left effectively used to take over almost all of our institutions, public and private over the last 60 years), acquiescence or Civil War. Those pretty much are the three options.
There's no need for Congress to get involved here. They already did what they needed to do when they passed the law that authorized the president to issue his Executive Order in the first place.
How much more involved does Congress need to be when you have Trump standing there this morning reading directly from the statute Congress passed years ago? LOL.
Hey now they are considering a carbon tax, give them some credit.
