What do you mean 20 years, in IT they already do that. And white guys are the first to go when down sizing. The reason you do not see it as such a major issue is that there is just not enough POC in IT to fill in the spots, the higher skill positions always seem to be whites and asians. While IT jobs become easier and easier it will become more visible but the discrimination is already here, it has been like this for at a decade.
