You're both likely correct.
We can afford to do it right. It will cost more and we'll have to make more prudent, effective, efficient, etc... decisions about producing and allocating goods and services and would need to give up many of the net negative/zero economic activities we like.
We've also likely enriched ourselves by externalizing the negative externalities of some of our goods and services to other countries. That's our choice, and I don't think it's a great one.
