Of my cohort of 15, I think over half are developers, a few are in other product roles at startups, and 1 or 2 went back to their previous jobs.
The laws are also outdated and not very practical- in California, which has some of the most rigorous regulations on environmental health, the test for a flame retardant cushion is to hold a candle to a piece of foam for 12 seconds.
The Chicago Tribune did a series on the tobacco industry's role in getting brominated flame retardants into furniture, which I recommend reading for some context on the current US regulations: http://media.apps.chicagotribune.com/flames/index.html

I wouldn't have been able to teach myself nearly as much using online resources. I learn much better being accountable to a group for my work, and there were so many times I got stuck and needed to just ask another person for help. I also learned how to work on a dev team, not just in my app-building silo. So, GA was worth it for me.
That being said, it depends on your background and your goals. Learning front end to change careers is different than learning it to be able to better communicate with front end devs at your work.
I personally wouldn't get $10k worth of knowledge from online resources, but your motivation may vary.
