I am also, I must confess, a little sceptical of the theory that we have a right, if we could, to pass on our capital burden to future generations. I remarked last year in this context that our predecessors had not passed any significant part of their burden on to us.

Money cannot be converted into houses or trained teachers or hospitals at the touch of a magic wand. There are limitations to our physical and intellectual resources.

Official opposition to overall economic planning and planning controls has been characterized in a recent editorial as "Papa knows best." But it is precisely because Papa does not know best that I believe that Government should not presume to tell any businessman or industrialist what he should or should not do, far less what he may or not do; and no matter how it may be dressed up that is what planning is.

I largely agree with those that hold that Government should not in general interfere with the course of the economy merely on the strength of its own commercial judgment. If we cannot rely on the judgment of individual businessmen, taking their own risks, we have no future anyway.

Over a wide field of our economy it is still the better course to rely on the nineteenth century's "hidden hand" than to thrust clumsy bureaucratic fingers into its sensitive mechanism. In particular, we cannot afford to damage its mainspring, freedom of competitive enterprise.

I hold that two principles are important; first that there should be a steady expansion of public services, not an irregular one related to revenue accruing in any particular year; the second that taxes should be constant over long periods (provided, that is, that they are neither burdensome nor inequitable).

The fact that previous generations have handed down to us a substantial public heritage by way of roads, port, etc. almost completely free of debt, seems to me to impose some limitation on the validity of the theory that by borrowing we should, or could, pass on the burden of development to the next generation.
