One is that by the very order of things such evils are not demonstrable until they have occurred: at each stage in their onset there is room for doubt and for dispute whether they be real or imaginary.By the same token, they attract little attention in comparison with current troubles, which are both indisputable and pressing: whence the besetting temptation of all politics to concern itself with the immediate present at the expense of the future.
Both answers are part of the official policy of the Conservative Party.
It almost passes belief that at this moment 20 or 30 additional immigrant children are arriving from overseas in Wolverhampton alone every week - and that means 15 or 20 additional families a decade or two hence.
Nobody knows, because no such policy has yet been attempted.
I can only say that, even at present, immigrants in my own constituency from time to time come to me, asking if I can find them assistance to return home.
In 15 or 20 years, on present trends, there will be in this country three and a half million Commonwealth immigrants and their descendants. That is the official figure given to parliament by the spokesman of the Registrar General's Office.
There is no comparable official figure for the year 2000, but it must be in the region of five to seven million, approximately one-tenth of the whole population, and approaching that of Greater London.
If such a policy were adopted and pursued with the determination which the gravity of the alternative justifies, the resultant outflow could appreciably alter the prospects.
The third element of the Conservative Party's policy is that all who are in this country as citizens should be equal before the law and that there shall be no discrimination or difference made between them by public authority.
I simply do not have the right to shrug my shoulders and think about something else.
