I don't think it's wrong they're doing what they're doing. I think inevitably most will "grow up" eventually and settle down to "normal" lives. Some may be mentally ill in some way and would be doing this sort of thing whether or not it was a "movement" - and it's good that they have others as well in the community.
And actually, I think it's morally wrong that in this day and age, someone CAN'T "live off the land" (whether it's in the back woods somewhere, or in the middle of the city) without someone getting offended that they're not living a more typical existence. If, as a human being, you're not allowed to fend for yourself without people talking about why you're not earning/spending money "like everyone should" - that's weird to me. Obviously most people will live conventional lives, and often those lives don't appeal to large segments of the society. How you differ will vary in degrees. I'd wager that most people on MDC come here because it's already a little bit alternative. I don't see this as being that much different. They're just a little further from the mainstream than most MDC mamas.
And the whole "race and class privilege" argument is beyond me; if you're white and have parents who were middle class, then you have to live a "nice, normal, mainstream" life? Or somehow because you're white you waltz into a courtroom and the judge says, "hey, you're white and your parents have money; I'll just sign you over the house, here ya go." Don't think it works quite like that.
Not to mention that a college degree doesn't guarantee much anymore anyway. I have a college degree. At this point I'm pretty much overqualified for a minimum wage job and I don't have the job experience to get anything else since I'm a SAHM. Especially in this job market. College schmollege. I went to college IN Buffalo, ironically enough, and believe me - the abandoned neighborhoods are like something out of Fight Club. I could totally see people squatting. And why not? People DO "throw away" houses - beautiful, large houses that are in need of love. If no one wants the house, why can't people use it? Personally I think I would be a little tidier than they are (I wouldn't strew junk around the place and make mobiles with old pots and pans, probably) but whatever.
Cleaning an abandoned house and growing a garden in the back doesn't strike me as that weird or radical, honestly. It seems logical. I probably wouldn't take it as far as they do but I really can't judge them too harshly.
And just a last note - central heating... don't we (generally) admire those MDC mamas who live in cold climates without central heat? But what they're doing is wrong? The winters ARE cold in Buffalo but for a few months we (poor college students) got by without central heat too and wow, we made it, no harm no foul.
