Initial thought:
Everyone is nudged slightly closer to what they need to live comfortable lives
For people with very low quality of life, their life gets slightly better For people with very high quality of life, their life gets imperceptibly worse (but then also slightly better as the world around them has improved, since they make up such a tiny fraction of people)
"more realistic" thought: The human brain is slightly less prone to addiction - however slight this adjustment needs to be to be considered a small thing.
Less social media addiction, less harmful substance addiction, less sugar addiction, less gambling addiction.
