The experience of France in the attempt to exact coal by the use of military pressure throws a good deal of light upon what is really annexed when a victor takes over territory containing, say, coal; as also upon the question of getting the coal when it has been annexed. 'If we need coal,' wrote a Paris journalist plaintively during the Spa Conference, 'why in heaven's name don't we go and take it.' The implication being that it could be 'taken' without payment, for nothing. But even if France were to occupy the Ruhr and to administer the mines, the plant would have to be put in order, rolling stock provided, railroads restored, and, as France has already learned, miners fed and clothed and housed. But that costs money--to be paid as part of the cost of the coal. If Germany is compelled to provide those things--mining machinery, rolling stock, rails, miners' houses and clothing and food--we are confronted with pretty much the same dilemma as we encounter in compelling the payment of an indemnity. A Germany that can buy foreign food is a Germany of restored credit; a Germany that can furnish rolling stock, rails, mining machinery, clothing and housing for miners, is a Germany restored to general economic health--and potentially powerful. That Germany France fears to create. And even though we resort to a military occupation, using forced labour militarily controlled, we are faced by the need of all the things that must still enter in the getting of the coal, from miners' food and houses to plant and steel rails. Their cost must be charged against the coal obtained. And the amount of coal obtained in return for a given outlay will depend very largely, as we know in England to our cost, upon the willingness of the miner himself. Even the measure of resistance provoked in British miners by disputes about workers' control and Nationalisation, has meant a great falling off in output. But at least they are working for their own countrymen. What would be their output if they felt they were working for an enemy, and that every ton they mined might merely result in increasing the ultimate demands which that enemy would make upon their country? Should we get even eighty per cent, of the pre-war output or anything like it?[14] Yet that diminished output would have to stand the cost of all the permanent charges aforesaid. Would the cost of the coal to France, under some scheme of forced labour, be in the end less than if she were to buy it in the ordinary commercial way from German mines, as she did before the War? This latter method would almost certainly be in economic terms more advantageous. Where is the economic advantage of the military method? This, of course, is only the re-discovery of the old truth that forced or slave labour is more costly than paid labour.
