This is a personal frustration of mine, and it happens in nearly every field. "Loudly talk about how terrible problem X is" and then go back to work everyday making X worse.
Software Developers decry the immense complexity of software, and then walk into work and load up five package managers on top of one another and npm install left-pad or whatever. Urbanists / Urban Planners decry the cost of housing and lack of transit, then go to work everyday and rapidly increase the cost of housing and eliminate transportation access. Education that used to cost $4k/yr now costs $40k/yr. Healthcare costs are rising exponentially and life expectancy is dropping. People complain about corrupt politicians doing bad things, and then go and vote for the corrupt person with the party affiliation of their choice.
"Things may be getting better" in the most general sense or at the most base levels. I don't dispute that. But 100% solved (or mostly solved) problems are becoming rapidly unsolved at a scary rate, and it's affecting a lot of regular people in bad ways.
