The Forbes article is focused on heavy industrial manufacturing, which is obviously a subset of manufacturing in general. The WSJ article is a short piece about the steel industry in America, and how it relates to China. The only American city mentioned in the 9 paragraphs of that article is Detroit. It doesn't mention any states. And the steel industry and the manufacturing industry are not the same thing. The third article... wait, did you even read any of these? You realize that the third article is a PDF from the EPA titled "Economic Impact Analysis of Proposed Iron and Steel Foundries", correct? I was asking you for citations to support your claim that other states make "far more stuff" than California, I wasn't looking for an environmental impact assessment surrounding the iron and steel industries.
Here is what I see. I see that California has over 1.2 million manufacturing jobs (the US has around 12 million manufacturing jobs in total). Second place is Texas with 847k, then Ohio with 660k, and down the line. Are Ohio's 660k jobs somehow more "impressive" than California's 1.2 million jobs, considering the disparity in total population? Maybe. Does Ohio make "far more stuff" than California? No. Or, at least if they do, then their workers are working at about 3 times the efficiency of the workers in California.
From the same article:
The National Association of Manufacturers (NAM) notes that manufacturers in California account for 11.2 percent of the total GSP (2011), employing almost 9 percent of the work force. Total overall output from manufacturing was $229.9 billion in 2011, significantly higher than in any other state.
Emphasis mine.
For its part, Ohio produced $80 billion in manufacturing output, which is actually 5th in the nation even though they have the third highest number of jobs (source). So California's output was just under three times as much as Ohio's output, even though California has just under twice as many workers.
There is still quite a bit of actual heavy industry in the state, but given its size and population the claim that it's particularly friendly is nonsense.
That's fine, keep that statement in mind the next time you see someone claim that California is particularly friendly to heavy industry. I haven't made such a claim.
In fact, the numbers are probably far worse by now. That's how it was over a decade ago. I know you're not too young too remember...
Instead of coming up with a new unsourced claim, it would have taken less time to just say "I made that up."
