Ok,
"African American children are three times more likely to live in poverty than Caucasian children. American Indian/Alaska Native, Hispanic, Pacific Islander, and Native Hawaiian families are more likely than Caucasian and Asian families to live in poverty (Costello, Keeler, & Angold, 2001; National Center for Education Statistics, 2007)."

Much more interesting tidbits there and how victimizing yourself or other Asians isn't getting you any sympathy. Sorry, but there isn't an equal number of poor blacks, whites, hispanics or asians. Maybe aside from certain European groups, only whites haven't dealt with any prejudicial hardships.
I'm not belittling Asian's previous struggles and achievements, but as stated before, asians performing well on standardized tests does NOT correlate to being a good physician. Facts are as a minority group you are doing far better socioeconomically than other minorities (source above). Hell, studying for the MCAT is already a financial burden that is difficult for people to afford and factoring in interviews, applications and all that jazz. It really is difficult for families to absorb those costs and have to take out loans JUST to gamble on an acceptance.
OP I think anyone, including asian, who works hard enough will make it into medical school, but facts are people of lower socioeconomic backgrounds just aren't likely to be physicians due to lack of resources and asians just aren't statistically known for being on the lower end of the spectrum.
