Sweden is the year 2019 17th richest country in the world. We have a good tax base. To maintain purchasing power and for the sake of fairness, we need pensions at a reasonable level. The compensation rate or pensions' share of the final salary decreases with each generation. For more details, see what the Swedish Pensions Authority writes here.
The pension payments build in first hand on tax revenue. No amount of savings is enough for the pension payments.
Even refugees need to have a decent pension. In order to receive a guaranteed pension, it is required that the person has lived in Sweden for 40 years. The guarantee pension in 2018 corresponds to no more than approx SEK 11/month, including housing allowance. 10 years of work should be enough to raise the level from the guaranteed pension level. Today's calculation of the requirements to get a decent level of pension is based on everyone being healthy for most of their lives and recessions being short-lived and occurring roughly every 45 years. Since around 1990, we in the western world have had financial crises every eight years and permanently high unemployment and high sick leave rates.
Daniel Ankarloo, PhD in economic history and lecturer in social work, writes in a debate article in Göteborgs-Posten 2012 that Sweden can certainly afford good pensions. Welfare funding in general is also no problem.
Today, public health is threatened by escalating burnout and worries about the future. Since 2010, the number of sick leave due to stress has increased sixfold. Isn't it so strange if anxiety about the pension plays a role in the mental illness?
