Responding to the OP...

I don't think you can rule education out... it would be suitable for some boys. I think the issue is many "sensible" farang would just think this is the best way to go so education becomes the "default" way to help and Isaan boy... which is wrong because it's not suitable for every boy. You're definitely right it's not realistic for every boy... and formal education is definitely not a pre-requisite for success.

I like the idea of funding a business... especially through a loan (I think most farang just give the money to the boy to start the business... loan is better) so he feels more self sufficient (i.e. he did it himself... all you did is offer a little "boost").
