For 30+ years, Western countries have been papering over the decline in living standards by issuing debt. In its simplest rendering, sovereign nations spent more than they could collect in taxes, so they issued debt (borrowed money) to fund their various welfare schemes.
This was usually sold as a “temporary” issue. But as politicians have shown us time and again, overspending is never a temporary issue. This is compounded by the fact that the political process largely consists of promising various social spending programs/ entitlements to incentivize voters.
