I kind of forgot about 3-D printing. I'm not really sure why. I do remember, however, when I first heard about, and since, that this is what I've been waiting for. For that technology to be used to build shelters.

I think a car will still remain a necessity to most. In more populated areas, probably not, but in rural areas; it's certainly necessary for emergencies. However, an emergency vehicle does not necessitate payments, if that's it's only use.

Great post, cheers! :)
