In this thread from /r/Catholicism, which is, most certainly, a trainwreck, I found this image, helpfully entitled 'Serf vs. Wagecuck'. BEHOLD ITS GLORY.
I mean, most people would look at the term 'wagecuck' and rightfully dismiss this as ignorant balderdash, but still. BEHOLD ITS GLORY.
Done beholding? Good. Let's go down the list.
The painting used to depict 'serfdom' does no such thing. It's a work by a 20th century German painter named Adolf Wissel. Adolf was, as it happens, an actual, card-carrying Nazi; his work was meant to portray an idealized version of rural life in accordance with the National Socialist ideology of Blut und Boden. More, his works feature German peasant families of the late 19th or early 20th century (I'm sure an actual German historian could narrow it down more specifically), while serfdom was abolished in Germany between 1770 and 1830. Actual medieval serfs looked something like this.
Under the painting, the creator of this image makes certain claims about the lives of serfs. To wit:
marry a 17 yo virgin with the finely sculpted body only regular physical labor can imbue
Well. Um. Exercise and a good diet makes people shapely. Hard labor breaks them. I don't have statistics on the physical appearance of serfs, but I have lots of old family photos (early 20th century) of people who spent their lives on their farms, and 'finely sculpted' is not the word I'd use. As to the rest, well, 17 is in the right age range, but virginity? Depending on the location, not so much. Peasant teenagers, it seems, would do a lot of sleeping around, and when a girl got successfully knocked up she'd marry the (probable) father ASAP. I'm inclined to imagine teenage serfs doing similarly, even though, in most places, there were restrictions on serf marriage; more, though this bit of propaganda is probably exaggerated, it's likely that serfs in Russia, as well as other places, were sexually as well as physically abused by their masters.
1/3 of days feast/celebration days
This one is actually true - at least in some times and places - but misleading. The author is trying to compare serfdom with modern 'wage slavery', i.e. the standard 40-hour week, and counting Saturdays and Sundays off (2/7 days) gets one close to the feast day schedule (2/6 days), and then you factor in vacations, holidays, sick days... and I would note further that a serf owed labor to his lord first, and then would go home and labor on his own fields/crops. While the average number of work hours might be the same, working sunup to sundown in the baking sun (during planting and harvest) is not exactly comparable to eight hours in a cubicle. And, again, this depends on where and when you were a serf - accounts from Russia claim that serfs would be called to labor sunup to sundown on their masters' fields, leaving them only the night to cultivate their own.
live in a warm, high-trust, multigenerational household
Three generations in one room with a dirt floor and infrequent bathing. Lovely. Again, true but idealized - serfs were not necessarily any happier with their marriages, families, mothers-in-law, etc., than people today.
no modern information technology to interfere with your religious belief - you have no doubt that eternal paradise awaits you upon death
Ignorance is bliss, huh? Leaving aside the whole bit about 'modern information technology' being responsible for religious doubt (unless we're talking about the printing press - hi, Martin Luther!) I'd just note that hope of eternal paradise went hand-in-hand with fear of eternal damnation. More, I want to emphasize that ignorant doesn't mean stupid - peasant and serf communities were hotbeds of religious debate (what else do you do after dark? Besides screw?), which sometimes led to heresy or encouraged open revolt.
eat natty grassfed dairy and organic produce every day
... if, by organic produce, you mean grains in various forms, sure. Dairy, yeah, cheese and butter were common, and livestock supplied important nutrition. Which is awesome, when there's water to grow crops and grass for livestock to eat. In the winter? During droughts and famines? Not so good. And famine was common in the Middle Ages.
Yeah, yeah, low hanging fruit, I know. But sometimes the low hanging fruit is so juicy and delicious that you just have to bite.
