>>6%.

LOL. Actually that's true shortly after you outsource manufacturing to China: your buy price falls by order/s of magnitude while your sell price may fall a few points for a little while. Kaching! goes the cash register.

IMHO consumers are about to experience a shock. Satisfied with its level of world dominance, the Chinese government is withdrawing cheap government money for manufacturing and is setting environmental standards, causing small factories and manufacturers of dirty products, to fold. Watch what happens to buy prices now. Elites awarded themselves a few years of extra dividend at the price of millions of mostly black US workers out of a job and manufacturing now irreversibly centered in China, with buy prices little different than they ever were. I say "irreversible" but actually that's not quite true. Reducing US corporate tax rates to (say) 20% might tip the scale to bring jobs and value-add industry back home. I guess we'll find out soon enough.
