Long, don't read unless bored or interested in the subject.
It makes sense to me, increased knowledge, education and access, while simultaneously being more disgruntled or less content.
Situations have greatly improved in many areas around the world but so has the knowledge of what is still lacking.
Example, China:
My guess is many that lived through the times of much worse oppression, may very well be appreciative of the strides made.
But for those that developed awareness at the time of change, or later, they also have knowledge of how much different/better things could be still.
Story from a friend.
US group visiting a sister company in China. There were US welders along and when they toured the welding facilities in the China location, they witnessed something shocking (to US welders)
The Chinese didn't have welding helmets. Instead, they had a piece of cardboard with a viewing hole and tint to view through. Which had a tendency to catch fire in their hands.
The US guys went immediately and purchased helmets for the others.
Obviously the locals conditions and circumstances improved immediately but so did their awareness. Their counterparts doing the exact same job in the US, could not only afford their own safety equipment but could afford to provide for them also. Their appreciation and conditions were both at a higher level but so was their understanding of how things "could be".
This was a simplified microcosm example but it can be applied in theory to the larger discussion.
I've openly shared my health struggles, a long with the financial disaster left as a result.
I'm very much aware and appreciative of the advancements allowing me to live and a possible chance to even partially recover.
But I admit, I'm also fully aware that I, and many others that have dealt with medical and resulting financial ruin, understand that it didn't have to be this extreme.
With our improved social conditions, we've also increased our knowledge of how far we have to go and the unnecessary barriers that we, as a society, have placed on ourselves. Knowing these examples are taking place in 2 of the wealthiest, most powerful countries on Earth that have the capabilities to resolve or lessen the situations...
Sometimes ignorance can be blissful and "he who increases knowledge, increases sorrow"
