Historically and presently, there is (reasonable) opposition to such ideas:
The reasons for the opposition by the Social Democrats have been clearly stated by Eero Heinäluoma, one of their leaders, in a public debate for the 2007 election: “Basic income encourages inactivity, is too expensive, means just an additional system among the others and does not support Lutheran work ethics.” Their position probably also has a lot to do with the links between the Social Democratic Party and the trade unions, who are totally against the idea of an income which would not be linked to work, would certainly lead to a reduction of salaries, and benefit mainly employers in line with Milton Friedman’s proposal. However, there has not been in 2015 really strong positions against among the social-democrats.
However, here’s some extra motivation for exploring the ideas of negative income tax, basic income, participatory income:
Behind the implementation of the basic income, there is the question of the status of work in the country. In European countries, we have arrived at a situation where large numbers of people are unemployed, with very little chance that these numbers will go down in the near future. This is particularly due to the (proven) fact that automation and robotization are destroying more jobs than innovation can create.
This should push us to think about the possibility that this could be a permanent situation, where we will need fewer workers to produce what we need. In addition, with the reduction of resources on the planet, an ever-growing production does not seem so realistic. Some are underlining that we are entering a new era, and the present social systems and its usual tools may be inadequate, as it proves that poverty and social problems have increased in the last years without any serious sign of improvement.
