Firemedic - chances are you're confusing "furniture building" with "fine furniture building".
You see, I can make a dining room table with 2x4s and pocket screws and it'll be 100x better than a dining room table bought at IKEA if for no other reason than the fact that it's made out of WOOD. It'll last longer, it'll survive moves, etc.
Now - would my dining room table sell at a local gallery? Absolutely not. It's not fine furniture. But it will be a place where many meals can be served and many memories made. And it won't hurt at all when I replace it with something nicer.
For young families these days who are struggling to get through, pocket screws have been a God-send. Most barely-knowledgeable home owners now can pump out a house full of furniture using ana-white or similar sources for half the price of IKEA even.
