This is simple math. Personally, after reading this bit of your post, I am starting to believe your posts deserve to be downvoted. I do pity you though.
Asians make up 5.5% of the population of the US, this includes all Asians. I don't have figures for their representation in the tech industry at large but some quick googling shows they make up some 39% of Silicon Valley workers.
African Americans make up 13% and Latinos 17%, which means for every one Asian worker in tech, we should expect around two to three African American and Latino workers.
I don't think there should be quotas but the tech industry demographics do not come anywhere close to tracking with our country's demographics.
Every industry ranging from Construction to Accountants has gender/ethnicity disparity.
