Housing affordability hasn't gone worse. People are picking on particular markets, but overall, especially in developed countries, it isn't getting any worse: inflation-adjusted price per square foot doesn't change over time, and average house size grows together with inflation-adjusted income. There are a couple exceptions (UK, Australia, Canada) but there are also opposite exceptions (Italy).

Environmental pollution especially in developed countries is now way lower than in any point in the living memory, plus quite a bit more. In developing countries, it's hit and miss.

Democracy only went down recently because it was forced upon many countries simply due to their defeat in the Cold War, those countries never been democratic before, never had any internal impulse to become democratic, and their peoples despised democracy and wanted this chaos to end as soon as possible. Reversal from artificial, externally forced democracy made vast majority of them happier. In many cases, their entire culture, religion and language itself precludes sustainable democracy. "Freedom" is not the universal desire of all people, time to get over it.
