It's not foreign wrestlers they treat poorly it is wrestlers without great English skills. Wrestlers from English speaking countries do very well, such as William Regal, Fit Finley, Kofi Kingston, and Vladimir Kozlov. However coming from a non English speaking country means you can expect to be a Mexicool or have your promos dubbed in the style of b-kungfu movie.(Which for the record was hilarious when they did that with Kaientai.) Mic work is perhaps overly required of WWE talent because the notion of having a manager talk for otherwise talented wrestler has been completely forgotten. Also WWE refusal to acknowledge anything non-WWE bassically makes anything wrestlers may have done in Japan or Mexico non-existant, which makes huge Japan stars nobody in WWE. Unfortunately the sytem seems stacked against some foreign talent, notably wrestlers from Japan.
