In his statement, Wieland points out that the term "investment" in the public debate does not comply with official statistics. e.g. building schools ranks among capital expenditures whereas the personnel spending for the teachers counts as state consumption.
In his view, the debt brake does not pose constraints on investments. He argues that currently and in the future, there is enough room for maneuver in order to incur the necessary expenditures with regard to climate change and structural change.
