One of the most elementary propositions of the science of economics is that the higher the price of anything, the smaller is the quantity of it that will be purchased. This applies to labor no less than to goods. If wage rates in Bangladesh are arbitrarily increased, fewer workers will be employed in Bangladesh. In that case, workers who would have earned low wages will earn no wages. They will starve. If employers in Bangladesh are compelled to make improvements in working conditions of a kind that do not pay for themselves, the cost of those improvements represents the equivalent of a rise in wage rates. Again, there will be unemployment ..
These are not outcomes that the advocates of imposing labor standards want. What they want is higher wages and better working conditions. Their problem is that they do not realize what is actually necessary to achieve these results.
What will achieve these results is leaving business firms in Bangladesh and throughout the Third World alone, to be as profitable as they can be.
Economic freedom, not government interference, is the road that the wealth of nations travels.
