I'm in Canada, so not strictly in your "American" category but close enough to comment.
Yes, there are loads of woodworkers on youtube- myself included- but I have no ads running on my channel, which is mainly focused on hand tools. In fact, hand tool woodworking is huge over here- just look at all the nascent toolmakers and well-established ones such as Veritas and Lie Nielsen, and writers and presenters such as Roy Underhill and Chris Schwarz. People just don't shout about it as much as power tool people, and the hand tool market is much more fragmented than the huge power tool companies which dominate advertising, Home Depot, tool shows, etc.
Of course space is not an issue for some- it's a huge continent- but most people work out of their basements or garages. I myself rent a 250 square foot workshop in an old industrial building because I can't use my house, and working in the garage when it's -25 degrees Celsius outside is not much fun!
Cost-wise we certainly get a better deal than in the UK. Life in general is cheaper here. That's just the way it is.
Anyway, I wouldn't extrapolate from a few muppets on youtube about the woodworking habits of an entire continent. From the people I've met at shows, classes, workshops etc. they're mostly very pleasant, down-to-earth people who are similar to English woodworkers.
