The problem with this parable is that it equates two different scenarios. A fisherman without extensive financial resources is not the same as a person with extensive financial resources choosing to fish. Here's some alternative endings, in a country without social and medical support in place, for you to consider:

1. The fisherman develops a serious illness and finds he can no longer support his family. His wife, who was barely getting by on a fisherman's income as a housewife, finds herself working at a local bar, serving drunk, lecherous men every day and night. His son and daughter find themselves unable to afford an education and really don't want daddy to die. With mounting medical bills, the son finds himself involved in crime to support his family and is eventually sent to prison for life for a crime he didn't commit. The daughter meets a wealthy man and everything is great until he starts hitting her. But at least she can support her father, lying on his deathbed in hospital. Daddy eventually dies but by that point she's stuck with 2 kids married to a man she hates.

2. Oh but medical welfare would solve the problem in #2? Setting aside that this is contrary to my stated scenario (a country without medical welfare), consider this scenario: the fisherman loses his fingers and toes in a freak fishing accident.

3. Oh but somehow he managed to afford an insurance policy that paid out on disability? Setting aside how unlikely this is to be for people barely making a living wage, consider this scenario instead: the nearby waters are polluted by an American oil extraction firm, and the fisherman finds himself scrubbing toilets at McDonald's to support his family. The American happens to come by one day and leaves him a nice tip.
