A Universal Basic Income Will Never Happen

The idea to provide everyone with a basic income exerts a strong intellectual appeal towards both the left and right side of the political spectrum. The appeal for left is that a universal basic income that is sufficiently high can ban poverty. For the right, a universal basic income is popular because it will remove the unemployment trap. In the current system of unemployment benefits, the unemployed lose their benefits upon finding a job. That discourages the search for a job. This shortcoming disappears with a universal basic income. Because in that system, the unemployed retain their basic income after finding a job.
AffordabilityWith such broad support you would expect that the universal basic income is already a reality. But that is obviously not the case. And that has everything to do with its affordability. Due to the fact that in such a system everyone, both rich and poor, working and non-working, receive the same basic income, the government requires to organize a massive money stream.
A numerical example: Suppose that the universal basic income is 1000 EUR per month (which is not that much if it is intended to ban poverty entirely) and that the basic income is given to all adult Belgians. This would mean that government expenses would increase by 100 billion, or 25 percent of GDP.
The universal basic income of course makes it possible to save on large portions of social security. Unemployment benefits and benefits for illness can be scratched; we could also save on pensions. But an important part of social security is not dropped. For instance, health care, child support and the portion of pensions above 1000 EUR remain.
Andreas Tirez from the think-tank Liberales has done an interesting exercise on the subject. He came to the conclusion that after deducing the savings on social security that would become possible through the basic income, there is still a shortage of about 35 billion EUR. That is about 9% of GDP.
It then also means that, after the introduction of the basic income, tax revenue would have to increase by 35 billion. The total tax burden that now represents about 51% of GDP, will need to increase to 60% of GDP.
Weakening work incentivesOne can argue over these numbers. Do they overestimate or underestimate the costs of a universal basic income? The reality will not be far off in my opinion.
A universal basic income that has the ambition to ban poverty from the world, is then immensely expensive. That doesn’t need to surprise you. To give the poor (a minority in society) a basic income, you have to also provide a basic income to the large majority that doesn’t need it. This leads to new problems. The working majority receives a basic income that stands loose from labor efforts, but will have to pay extra taxes (and not a small amount) on their labor incomes. And that is the best way to weaken work incentives.
Conclusion: The only realistic system is one where the basic income is limited to those who need it. A universal basic income will never happen.
