As a former “text book” leftist I am inclined to agree that good will alone is not enough for humanity in its current state to operate a society on, and that many current day leftists are wearing the same rose tinted goggles for the USSR and China that the right wears for the 50s.
We need both incentives as well as strict limits to remain within healthy behavior at large, otherwise we end up with apathetic full time unemployed people on the lower end as well as cancerous outgrowths like individuals possessing billions, living like feudal lords of medieval times.
Incentives tied to employment in the current form are not practical any more though. With continuing industrialization, automation, and the emergence of artificial intelligence on the horizon the economies of the world simply don’t need those people as workers any more. This leads to the UBI as the next logical conclusion to provide the consumer base our economies depend on with disposable income to participate as well as a means of securing their essential needs. This then means the incentive must be different, personal ideas are to tie the UBI to the individual being at least x hours per month engaged in some kind of productive and/or creative outlet, be it education, community work, pursuing interests, or some other form of value provided to society based on the individual‘s interests and abilities.
Basically the Star Trek federation philosophy of personal improvement (enhanced with some basic incentive to participate), mixed with the communist idea of assigning professions based on ability, except with the individual freedom to choose instead. Do something worthwhile, and if it’s just pursuing a hobby, and thats good enough.
You don’t need “an opinion” on that, it’s a simple fact for decades now. The polish people are largely devout christians, voting religious right wingers and populists into office. They in turn weaken the polish democracy to further secure their power.
