“…Finally, the previous insights about static and dynamic interactions between religious and secular ethics seem to be empirically supported by the observed dynamics of education achievements, religious believers and life satisfaction in OECD countries from 2000 to 2020. Indeed, consistently with the theoretical insight by Schopenhauer (i.e., religions represent metaphysics of people and an increase in tertiary education within a cultural individual perspective cannot compensate for a decrease in believer proportion in providing a meaning to life) [ 73 ]: education quantity in primary, secondary and tertiary increased by 114%, 107%, and 143%, respectively (by reaching the practically highest possible 100%, 123% and 102% of gross enrolment rates, respectively, in 2020); education quality in primary, secondary and tertiary increased by 115%, 93%, and 96%, respectively (by reaching 5221, 5199 and 7022 USD per-student per-year education expenditures, respectively, in 2020); believer proportion decreased by 5% (by falling to 78% in 2020); HLEB increased by 7% (by rising to 72.32 years in 2020); and LS decreased by 1% (by falling to 6.74 in 2020) [ 74 ].…”
