It is apparently economic to do so in China and apparently any other place you want to outsource it to. Does smaller and one-off productions have as high of margins as high speed automated stamping machines running 24/7? No. But that doesn't mean it isn't profitable at all.

And quite frankly, who gives a fuck if top owners and investors get maximum returns, boo hoo they got 4% return instead of 8%, that is still far better than the average working class's deal. Our entire problem is a suffering middle and lower classes that need decent work, they will still be happy even if the product they make is a bit lower margin because they are paid hourly, not paid by dividends and stock options which is where all the higher margins profits go. Average citizens pay has not correlated with increased company profits, and increased company profits isn't what makes society stable, so the investor class is going to have to suck it up and take the hit unless they want their entire house of cards to collapse.
