Just ground the planes and withdraw them all from service. Let Boeing redo the whole system and get a new airworthiness certificate. Let them take another 6 months to a year to properly train pilots flying this plane. Yes, it may take 1-3 years, but rather safe than sorry.
Just bin the 737. Build a modern aeroplane that meets the new safety standards. The 737 has exemption for lot of the new safety things because they've been grandfathered into the type certification.

The sudden interest at all levels in the US is because more and more people are realising how serious this all is. The impact on the US economy is more than a bit significant. The Credibility of US Institutions is at stake. And of course, we have seen the first move to find and blame someone.
Trump gets off his arse and suddenly fills a vacancy in the FAA. The first step in blaming the current person holding the post in an acting capacity! They may or may not continue with all the "'investigations" or just let normal processes take over. Presumably, Trump's opponents are not going to let this golden arrow go to waste. They are going to squeeze it for every possible drop of blood they can.

All this in the hopes that this matter will fade out of the public domain as soon as possible.

I just hope they come clean with any other "tweaks" or liberties they might have taken with this new model.
The FAA will come under enormous pressure from Congress and the airlines to review the certification of the MAX aircraft. Having said that, the B737 has proven to be relatively safe (MCAS excluded) and reliable.

Every generation has its once in a lifetime events, and though not quite on a 9/11 or Titanic scale, this issue is likely to be remembered for a very long time.

Unlikely, it takes a decade to produce and certify a new aircraft.

The New York Times trying to defend Boeing and attempting to apportion some blame to Ethiopian Airlines -

https://www.nytimes.com/2019/03/20/world/africa/ethiopian-airlines-boeing.html

Ethiopian Airlines surpassed many carriers by becoming one of the first to install a simulator to teach pilots how to fly the new Boeing 737 Max 8, but the captain of the doomed Flight 302 never trained on the simulator, according to people close to the airline’s operations.
However, Ethiopian Airlines have had this to say -

A news article suggests that an important change to the control column stabiliser trim cutoff switch may have made recovery from a faulty MCAS activation more difficult: https://www.reuters.com/article/us-...ve-imperiled-planes-experts-say-idUSKCN1R322M

Much like tapping the brake pedal in a car to disengage cruise control, a sharp tug on the controls of older models of Boeing Co’s 737 used to shut off an automatic trim system that keeps the plane flying level, giving the pilot control.

But Boeing disabled the “yoke jerk” function when it brought out the 737 MAX, the latest version of its top-selling jet - and many pilots were unaware of the change, aviation experts told Reuters.

Excellent new video from Mentour Pilot, describing the stabiliser trim system, and demonstrating the procedure to stop runaway trim:
