Albert and Hahnel argue that it is inequitable and ineffective to compensate people on the basis of luck (e.g. skills or talents that owe to their birth or heredity), or by virtue of workers' productivity (as measured by the "value" of the goods they produce). Therefore, the primary principle of participatory economics is to reward workers for their effort and sacrifice. For example, mining work—which is dangerous and uncomfortable—would be more highly paid than office work for the same amount of time, thus allowing the miner to work fewer hours for the same pay, and the burden of highly dangerous and strenuous jobs to be shared among the populace.
