There has always been a "tension" between advocates of stricter codes for safety, vs. laxer codes in the interest of reduced construction costs. I have known building officials who came into the profession from being home builders, and they generally ranted endlessly about how all the "unnecessary" code requirements (which just means provisions they didn't understand) are there only to increase the cost of construction. I always suspected that those building officials basically turned a blind eye toward enforcing provisions they personally didn't agree with -- which, IMHO, is not a professional or acceptable approach.
So the U.S. has a "housing crisis." The reality is that there's no such thing any more as a "starter house," such as what my parents bought when my father returned from service during WW2. The house was a small two-story colonial-ish house with three [small] bedrooms, one [small] bathroom, a tiny kitchen, and a dining alcove (not a real dining room). My parents at the time had two children (me and my younger brother). It wasn't luxurious, but it was new, the roof didn't leak, and it provided far better shelter than what a huge percentage of the world's population lives it.
No developer today is interested in building such affordable starter houses. Today's "starter house" has at least 2-1/2 baths, a huge kitchen with granite countertops, a master bedroom suite with an "en suite" bathing environment, yada, yada -- and the base price before upgrades is half a million $$$.
So the political solution is to abandon decades of progress in building safety in order to lower construction costs -- which will just allow builders to keep charging the same prices but make more profit.
It's a race to the bottom. It won't end until people start dying, at which point the code pendulum will again swing in the direction of building/life safety.
