Are we really better off now, with economic crises every few decades, mass murder of children, widespread acceptance of perversion, and mass godlessness, than back in medieval Europe, where there was stability and order?
Really? Here, let me tackle these one at a time, ok?
Are we really better off now, with economic crises every few decades
The economy of the era was a complete shambles. Most "countries" simply reminted older coins, and coins of 100 or more years old were commonly found in circulation. In fact, hard currency was almost unheard of, most communities surviving off of the barter system. And this is a system that makes it almost impossible to save anything. You can't just take a pig or a bushel of oats and stick them in the bank.
And to show how bad the economy was, the smallest coins that were commonly in circulation were silver pennies, equivalent today to around $50. With the fall of the Roman Empire, all lesser coins (copper and bronze) were no longer minted. Imagine a world where the smallest bill available was a $50 bill. You can't just buy a pack of gum, you need to buy a case of it, because there was no way to make change.
And with no way to "save", all of your wealth is therefore tied up into production itself. Had a bad crop year? Well, you had better rely upon the charity of neighbors, because you have no money in the bank, nowhere to get a loan. This is why migrations were common, peasants being forced to move when their crops failed or a plague decimated their region.
Do you think the Pied Piper of Hamlin was just a children's story? The full version is often cleaned up for modern audiences, but in the original stories the ending was very different. Either the children were led into the mountain and never heard from again, they were taken to the top of the mountain and the Piper had his wicked way with them, or they were simply marched into the Weser River, to drown like the rats earlier in the story.
And most believe this story is based upon a real event. The "Children's Crusade". Where possibly as many as 30,000 children were convinced to go to the Holy Land on a crusade, only to be sold into slavery in Tunisia.
widespread acceptance of perversion
Well, during that era, the "age of consent" for girls was 12, for boys it was 14. Make of that whatever you wish. Adults in their 30's marrying a 12 or 13 year old girl was common practice during the Middle Ages.
As for the rest of your rant, seems you have some kind of fantasy belief of what the era was really like. If you were living in a more feudal region where serfdom was common practice, you were essentially a slave. You were tied to the land, and could not simply move without the permission of your lord. Disease was rampant, and many times saw plagues that were even worse then Ebola in West Africa today.
Stability and order. With constant invasions from various barbarian tribes, most of the countries we know of today at the time were actually composed of many smaller kingdoms. England as we know of it was actually much smaller kingdoms. Wales, Essex, Sussex, East Anglia, Northumbland, Mercia, Danelaw, Guthrium, and others at various times. During most of the Middle Ages, England was little more then multiple bandit kings who were constantly fighting one another. Until they were finally invaded by the Normans largely consolidated them through invasion and conquest.
And as a male peasant, you could be called up at any time as part of a military levy. Think of it as a forced draft, where your main purpose was to act as cannon fodder to absorb losses before the lord's men at arms entered the battle. So if the Baron who owned the land you farmed decided to go to war with another Baron over a grove of timber both wanted, you are forced into the army and marched off to fight. And of course the constant invasions by Eastern European tribes.
The Vandals were still moving through the area, as were the Goths, Visigoths, Franks, and many others.
And don't forget the Norse, who frequently invaded any land with a waterway, be it ocean or navigable river.
Oh, and of course the Moors. Who invaded what is now Spain, and controlled it as an Islamic Sultanate for over 770 years.
And of course all the migration because of these wars. Moors invade Spain, so many of the region migrate to France, which pushes more into Germany, etc, etc, etc.
