You are correct. However, let me throw this out there for consideration - is it possible that employers are reluctant to hire blacks because if they have just cause to fire them - then they face lawsuits and cries of discrimination? I know I was shocked to find out that the majority of blacks will use the race card to get their own way. So, the NAACP may have hurt the blacks more than help them.
The problem is that people can sue if you DON’T hire them. The government effectively enforces quotas.
