If 90% of the countries in the world are in debt and corporations have more money than god, then clearly the system isn’t ideal.
$34T is insane for one single country.
As for infrastructure, proper taxation of corporations would raise more revenue to fix such things. If Amazon is contributing to the breakdown of roads due to all the couriers then they should be paying more tax.
Look at the water companies in the UK. Paid out their shareholders for decades and did nothing to improve the infrastructure which is now likely to end up with them being nationalised after they’ve looted what they could.
