however, it doesn’t have to end this way how else can it end? 
well… the other 8 people that don’t have a boat 
they’re standing around on the beach

and one of those 8, a politician, starts giving speeches and telling that “ this is not fair” 
“we only can catch 2 fish a day and the people with the boat catch 10, the income used to be equal now is not”
“what if we raise a tax of 80% on anybody who uses a boat?”

and they take16 fish and they give 2 to all other 8  now none is better off
