The present isn't all that cute either. But if from the view of 100 years in the future, all you saw was the idealized lives of everyone as posted on social media, you'd think it was a lost, happy time too. That's how nostalgia works. You preserve the good stuff, you let the boring and crappy stuff be forgotten. At least relatively.
If the Canterbury Tales had been actually representative of the time in which they were written, it would not have been the Knight's Tale, the Miller's Tale, the Reeve's Tale, etc. It would have been the Subsistence Farmer's Tale, the Subsistence Farmer's Tale, the Subsistence Farmer's Tale, etc.
The Canterbury Tales were trying to show the viewpoints of people from a wide variety of social backgrounds.
But in this world the distribution of social backgrounds in the population had very low entropy. Over 90% of people were just working the land.
