Most of our infrastructure was built a long time ago (except roads) and don’t actively see maintenance. No one from the current generations has had to pay for real impactful infrastructure for decades. Now that all the infrastructure is failing or has security holes nobody wants to pay for it to be fixed. If you look up major infrastructure repairs in the last few decades you will see much of what could have been long term fixes were reduced to short term fixes.

Properly fixing infrastructure has become expensive as construction costs have skyrocketed in the last few decades.

Look at the CHIPS bill, huge infrastructure gain but also was a part of the 9% inflation because building this infrastructure is expensive. The American people were warned about it causing inflation but wanted it anyways. When inflation hit they all conveniently forgot the cost of new infrastructure in the US and chose to cling to lies about how disastrous the last 4 years have been.

That is why today no one does anything about problems until a bridge collapses. You can make more money today by passing the buck to the next generation and passing blame to whoever came before you.
