Some truth to that, definitely better for civilization when ppl lower their time preference.

At least when the discounting of the future (i.e high time preference) is caused by easy money it doesn’t necessarily follow that one must become self-centered. Families in poor countries can and usually have high time preference but it’s to satisfy their family’s present needs.

Time preference alone is not sufficient to fix a lack of virtue. Ppl also need to find God, or adopt Jesus’s teachings for their moral framework even if they reject Him as atheists do.
