In a free society (i.e., a society that recognizes individual freedom), the likelihood of segregation arising will tend to be lower. For most people, a desire for money outweighs bigotry. Segregation-based policies cost businesses money;
No they don't. The dominant group has far more money than the oppressed minorities. One's profits are enhanced by catering to their prejudices and banning the minority - who by definition are less numerous and due to power relationships less well heeled.
Of course they would! They would prefer all sorts of things, involving a less demanding and more foolish customer. But, alas for them, they must deal with what the customer wants, or lose him to their competitor. So a lunch counter that serves blacks will lose all its white customers (the bulk of its business) to the one round the corner that continues to ban them. The customer is always right, isn't he, Emsworth?
While most business persons are racists, you are right to note that the reason they exhibit bias towards their customers is not their personal hatreds so much as their desire for profit.
No.
This is certainly true - in fact it is through the excersize of State power on behalf of whites that they became the business owners in the first place, Emsworth.
