the cost of getting 'fat' in Vietnam

am emergency blip really - got a bad cold which has just slaughtered me.... dragged myself through the day with light work and slept at lunch instead of bear watching....
but thought this tin would amuse and thought provoke
it's very cute the way the title and drawing emphasize going from thin to fat (or well rounded) - we use it as a weight gain/nutritional shake for bears that are going off their food....
but the reality is the people who need this in Vietnam are the kids living in poverty
the tin costs $500,000.000 dong which is about $24 australian dollars and about a weeks wages for a villager that is lucky enough to have a factory job.....
the rich kids here don't need it..... so who the hell buys it I wonder? (except us)
