Why do you think it is bad for Airbus?

We all know the Max is currently going nowhere. Meanwhile, today I photographed what turns out to be the last 737NG to come off the production line, PH-BCL. So, if Max production is halted and no more 737NGs are to be built (at least for civil airline use), what will Boeing do to address the market for similar sized aircraft?

United Airlines have the MAX off their schedules until June this year, the groundings are being pushed further out in increasing amounts of time. When it was first grounded, the return to service was expected to be within a much shorter time frame and the extensions were done a lot closer to the original target. The days have turned into weeks and the weeks have turned into months. Not good.

In reality its bad for everybody. When you have one manufacturer, you have complacency. Competition does improve the breed.

I don't think there's much evidence that any nations are much interested in "fair competition" for players in industries important to their domestic economies. They all claim to be, of course, hoping that they can undercut any advantages competitors may have.

Sometimes, fairness is better honored in sporting competition.

And yet in this reality of this case, Boeing took shortcuts with safety in order to compete with Airbus. The facts are the opposite of your assertion.

As a general principle, perhaps, but imho aviation is not a typical industry. If there were only one major manufacturer of aircraft and they made unsafe aeroplanes, nobody would fly and the whole thing would collapse.

Rather than comparing size of company, I'd prefer to see comparisons based on safety and reliability.

The FAA is currently unable, by statute, to do what most people would consider to be "its job" in this area. That is the result of lobbying by "industry" (primarily a single entity) to have the Congress require full delegation to ODAs by the FAA. The FAA Reauthorization Act of 2018 includes, in Section 212 of that Act, several direct requirements and several other insidious requirements to fully delegate type certification to ODAs, even when past actions of an ODA have led to FAA retention of certain findings. Here's a link to that act. Section 212 is about 1/5 of the way down in the page. Read it. It's scary.

Unless the Congress changes the law, nothing in the type certification process will change for the better. I am concerned we are only beginning to see the negative effects of the transition to the ODA system.

Not really.
It is expected by manufacturers to occasionally take shortcuts, and it is expected by regulators and authorities to keep them in check.
My impression/opinion is that Boeing became complacent because of their position and their influence over the FAA.

Trump now says only deals that are a win for the US.

Exactly. But it is Trump, so it‘s gotta be wrong.
