Based entirely conversations with a few architects and interior designers, the incentives are almost always far more aligned with “cost-effective”/“inoffensive” than “innovative”/“striking”.
Architecture has always been strongly bifurcated with the (much larger) low end being dominated by cost/market considerations. But these architects do take design cues from the top of their field.
Low-end Italianate and Gothic Revival yielded the gorgeous Brooklyn brownstones. Low-end Corbusier yields the hideous, cultureless 5-over-1s perfectly prepared for a Chipotle logo.
