In the post about European semiconductor decline my comment about average citizens having to invest more, was massively downvoted. Since nobody will read my reply there, here is the quote from the Draghi report that shows why more private investment is necessary.

Unless you plan a revolution, please take a moment to read the quote.

The failure of high EU savings to flow into productive investments in Europe comes down to less efficient financial intermediation. The persistent shortfall of investment vis-à-vis the US has occurred even though EU households save more than their peers in the US. In 2022, EU household savings were EUR 1,390 billion compared with EUR 840 billion in the US, reflecting the lower savings rate of US households, which is around a quarter of the EU level04. However, despite their higher savings, EU households have considerably lower wealth than their US counterparts, largely because of the lower returns they receive from financial markets on their asset holdings.
