It doesn't matter if my grandchildren will benefit form an infrastructure built today. What matters is that if I am asking for it to exist I should pay for it.
Speak for yourself.
I'm delighted that previous generations have provided me with access to education, healthcare and modern infrastructure. And I fully intend to pass more of the same on to subsequent generations.
If you don't like it, MOVE TO SOMALIA.
I'm not even sure in what sense I've ever "payed" for it, or ever could. Some govt bonds were issued as a synthetic legal obligation, which are private sector assets, will never be really payed off but could be payed off at any time by central banks changing digits on spreadsheets.
The horror!
I haven't payed for it. The previous generations who created the infrastructure and institutions with ACTUAL WORK already payed for it
