The other thing to mention as to why everyone having aircon is not necessarily desirable is that it is an environmental disaster.
Heating is far worse, but I never see anyone complaining about that. If you try to take my AC away, I'll become a climate change denialist. 
If you can’t survive in a climate without air conditioning, then you’ve either never adequately adapted to that climate or it’s simply not one that your body can handle. I say that as someone who spent the first 23 years of their life in Florida with barely any a/c and who now lives in Vermont without any a/c. It’s an environmental disaster and harmful to your ability to acclimate. Do hot days (and especially nights) suck? Absolutely. Personally, I can tolerate the cold much better than the heat so the Canadian border states are as far south as I’ll live now. But it’s important to let your body acclimate to your climate; if you can’t handle that, then consider relocating. A/c units should, ideally, be reserved for those with health risks or at least not be used by the general public until heatwaves strike.
AC should've never been invented. Facilitated the yankee demographic swamping of Florida and the south
