What is the incentive to train or educate yourself?
A participatory economy does not pay those with more education and training higher wages since it would be inequitable to do so. But that does not mean people would not seek to enhance their productivity. The cost of education and training would be born publicly, not privately and so there are no material disincentives to pursuing education and training.
Since a participatory economy is not a society where people are judged by their belongings, but rather a society in which esteem and respect are based on “social serviceability,” there are strong incentives to develop one’s most socially useful potentials through education and training.
Anyone pursuing training in a participatory economy would receive income just like any other worker in the economy. If the training is deemed more onerous compared to the social average, a student receives more income accordingly, or vice versa.
