What followed was not necessarily even about cost-cutting - they wanted to spread out the production of their aircraft from centralized locations (easy to QC) to cover as many different congressional districts and reap the maximum amount of political capital.

Part of the problem is also that airlines have been very good at squeezing the duopoly while demanding ever more. The competition, if it manages to get a plane in the air, usually isn’t as fuel efficient and so the airlines have mostly not been interested.
To be fair, that's because Boeing forced them to sell the rights to the A220 for $1.

The USITC reversed their own decision a year or so later, and Boeing chose to not appeal the decision, but Bombardier and Canada ended up deciding to not pursue things further.
Russia might certify it unless having a viable domestic alternative. Moreover, it could reuse parts for its own planes.
These three taken together are already a significant chunk of the global market, each having a large domestic demand.
The problem with Tu-204 is that it wasn't a good market fit, like the current Chinese ARJ. It was certified OK and could fly abroad all right.
People said the same about Chinese cars and they're the largest exporter in 2023.
What if they have not one but ten generic passenger plane brands by 2040?
They demonstrated localized version of SSJ-100 with PD-8 engine in 2023. I'm not sure if it actually flew, but there were at least ground tests of the fully assembled aircraft.
I much rather fly in an E195 E2 than a 737 or A320 Neo. Really next level. KLM has these, unfortunately they rarely use them to my destination because they can fill a 737 to there as well :(
I'm also certain they don't want to.
Boeing is a duopoly with Airbus and for putting in your hands in a brand new Airbus you will have to join the queue and wait five years. So they benefit from the lack of competition, if the merger with McDonnel had never happened, probably this situation would be different. But today's capitalism is all about consolidating and eliminating competition.
Embraer might try to venture in the wide body segment, but they don't seem willing to do that move.
