perhaps, but all I really see as being necessary is the following:
Make it too costly to engage in cherry picking in the face of non-cherry picking competition. (for labor), and enforce complete transparency on human resource ethnicity data, coupled with strictly worded legal statutes to bind the hands of authority figures (for law enforcement.)
EG, Yahoo and Google both have very damning employment demographic statistics, that strongly indicate that they are in violation of the proposed precept. Evaluate the potential income advantage they seek to gain from this cherry picking, and fine them anually at 2x that rate, until conditions improve. Evaluate this figure against their combined international revinue stream. Their competitors with better hiring policies will have an economic advantage, and will quicky overtake them as long as they remain so encumbered.
Furgeson MO has very damning employment statistics as well, considering the local racial demographic. In addition to the above sanction, they would need to be barred from hiding the fact that the overwhelming majority of their officers are white, and have state level oversight imposed against them for operating under such conditions, such as being refused state funding for their police district, due to noncompliance. Additionally, carceration rates and statistics should be monitored and corrective action applied as needed for "selective enforcement" by thier law enforcement personel. (You simply cant hide the fact that you racially bias your arrests and traffic stops. It shows up like a sore thumb.)
Over the state level, federal oversight should ensure that state govts are in compliance, using witholding of federal funds as the cudgel.
You dont have to give an unfair counter-advantage. Just remove the already existing advantage, and level the feild.
This is a race-neutral solution, which would continue to work no matter which racial demographic holds the majority.
compared to the affirmative action verbiage, which is very explicit in which racial imbalance it seeks to address (and is thus, institutional racism)
