As for the suffering - I grew up in communism, or socialism, or whatever you want to label it, behind iron curtain. There was some child-like naivety in population, you can personally call it something positive but I do not. The rest - oppression from all angles, erasure of individualism, sometimes outright murder by system. This is reality of alternatives I talk about.
The medieval fairy tale you are getting from maybe some children's book wasn't true anywhere in Europe, that's pretty much guaranteed. Half of kids died before reaching 5, child births were often fatal for mothers so men had often multiple wives out of practicality. Tooth infections, appendix or flu were killing those older left and right, everybody smelled horribly due to simply not washing at all, had fleas and other parasites and infections. Those folks suffered in ways we can't even imagine, lived short lives full of hard work and often died of causes we simply don't experience anymore. Marriage around 14-15 with first child on the way right after was the norm.
> On balance, they were probably happier than modern man.
You don't know that, nobody knows and its not even comparable. Its true that if you are semi-constantly in survival situations and one bad crop will kill everybody you don't have energy to ponder on larger topics. You can easily create it on your own today if you want, nobody is stopping you.
