Basic income is no reasonable form of income. Such an income implies wrong incentives. It gives the impression that it is possible to get income without fulfilling demands of society. It may lead to the loss of the ability to work hard in order to earn money. Basic income will provide young people with enough money, but later in life they will feel as underachievers when they discover that their peers being employed earn much more money.
Basic income creates a fundamental problem: why should someone do a hard, but not well paid job like cleaning the rooms in a hospital, if basic income is available. It is no solution to pay higher wages for simple work, because money is not growing on trees.
The idea of basic income is mixing up two different principles: solidarity and performance-related justice. Solidarity provides persons in need not able to gain their own income with the necessary means to live a modest, but dignified life. Performance-related justice provides with fair payment for a work or service someone has provided. It seems unreasonable to provide someone with a basic income, who could do something society is willing to pay for. Why should society not demand something in return?
A passage in the New Testament says: “The one who is unwilling to work shall not eat“ meaning that everyone has a duty to do something society is in need. Who does not do something society is willing to pay for, should only be helped by solidarity if he or she is not able to do something for the society. The idea of basic income leads to believe in a land of plenty not respecting that money needs to be earned.
