I’m not the biggest fan of capitalism myself but the existence of debt does not mean it is broken. Debt is a mechanism to allow for solid investments, e.g. building infrastructure or schools that will create a net positive in the (far) future.
Germany for example has enacted a Schuldenbremse (debt-break) in 2009 and forbids our states to take on new debt and limits the debt taken on the federal level to a minisule percentage of the GDP. Our infrastructure is currently slowly but noticeably crumbling away, bridges are getting closed for heavy traffic and experts say many of them have become irreparable due to missing maintenance and need to be fully rebuild in a few years. The local military barracks are in such a desolate condition that the soldiers need to drive two towns over to shower. We might not take on financial debt, but an infrastructure debt that will demand an even bigger toll on us.
