In my opinion, most of the financial aspects (job stability, high-income, etc.) are not important for Westerners, as long as one has enough money or ressources to survive.
When I asked my husband to explain "tayorigai" to me, you know what he gave me as his first example? What he immediately thought of?

"If you had an emergency and needed $10,000(or lost $10,000, whatever), the person who is "tayorigai" would be the person you know you could trust to help you get it back(in other words, loan it to you)."

Of course, he went on to give other examples, and told me that really it meant trustworthy/responsible/reliable, but I just thought it was interesting that he gave me that as his first example. Especially since I read your last post, Maciamo.
