Other than defaulting on their debt, they can’t do any thing about it as the money was spent decades ago in the form of defined benefit pension payments in the future. If all the recipients of those future defined benefit pension payments died, then that would also lower their debt.
Hm, so currently they just "service the debt", they can issue bonds and just pay out over 50+ years. I don't see why they don't plan for the long term with this.
Though they should just ship pensioners to a cheap-to-live state, eg Florida or Pennsylvania.
Okay, okay, armchair policy recommendations are always very nuanced and great (not to mention useful), especially on random internet forums! But the level of dysfunction due to braindead leadership is always surprising.
