Empfängt der Schnitter (Joh 4, 36) schon seinen Lohn?

Laut Economist schon - jedenfalls in Amerika:

"Jonathan Gruber, an economist at the Massachusetts Institute of Technology, claims that regular religious participation leads to better education, higher income and a lower chance of divorce. His results (based on data covering non-Hispanic white Americans of several Christian denominations, other faiths and none) imply that doubling church attendance raises someone's income by almost 10%."
