FOOLEDNOMORE:
Yes, the sad story you told is related to the subject.
The common theme is somebody dropping out of the responsible ‘real’ world in order to ‘peddle the Witness dream’ - not unlike a JW not wanting to work/save for retirement, instead opting to be in the ministry.
There really isn’t any sane excuse to do what this man did (quit his job, right?). He would need good medical coverage and had to work in order to have it.. He would go on disability for the duration of his treatment. But he would still technically be employed. The treatments would mostly be covered and he would be responsible for copayments, etc. At least it wouldn’t be the disaster he left for his wife.
This isn’t the first time some JW mindlessly cast everything to the wind! Sounds like a child.. This is what happens in a group that cuts itself off from the rest of society and is not exposed to plain old common sense.
