Abstract
We are often told that we are morally obligated to produce equal opportunity for all. Therefore, it seems we should examine what power we have to produce that desirable state. For it would be nonsense to say we are required to provide what is beyond our power to provide. When we examine this question, we find our power limited by two sets of constraints. One set comprises formal constraints upon the idea itself of equal opportunity. We cannot do the logically impossible. The other set comprises limits upon our ability to produce the directed socio-economic change, getting known outputs for known inputs. I illustrate the formal constraints by outlining the work of Douglas Rae. The constraints upon our abilities I illustrate with evidence from sociology and politics. At the end, we shall discover that our power to make opportunities equal is sharply though not unbearably limited. A critical but unbaised survey will reveal that in the past fifty years we have gone remarkably far towards doing all that we are presently capable of doing to equalize opportunities. Perhaps we shall go even farther when we learn how. The word ‘real’ in the title is opposed to ‘ideal’ or even ‘chimerical'. It may seem an interesting question what equality of opportunity should consist in were we able to produce directed socio-economic change at will. But we are not. Therefore, a more interesting and more important question is what equality of opportunity consists in given the very large number of constraints within which we must work to achieve it.
