In addition to what's the article tells, you can get in china components you just can't get in the u.s. For example , the mt6250 which is 260mhz arm7 microprocessor, with 8MByte ram , with dsp, with cellular modem, with bluetooth and with all kins of IO.it can run a feature phone with touchscreen and run games. Or be a cool internet of things micro controller. Or. How much does it cost ? $2 in volume , in low volume you can maybe get it in $3 in china. But no way to get it in the u.s. . And i bet there are plenty of other gems available.
