As is depicted in the picture, compared to the situation in the past, nowadays the total wealth that mankind possesses conspicuously surpasses that of any time in history. What is more striking is that most of the wealth concentrates in the hands of a small bunch of people.

　　It is quite obvious that the artist wishes to set us thinking about the disparity between the rich and the poor in today's world(society) . On the one hand, it is staggering for us to find in the annual list of the "World's Wealthiest People" by Forbes Magazine how the property of the rich keeps aggregating in an unbelievable scale. For instance, the fortune of Bill Gates certainly amounts to, or even exceeds, the annual GDP of an average developing country. On the other hand, the majority of humans have to struggle simply to make ends meet, not to mention those(who) still suffer from hunger in the most less developed countries.

　　It is beyond doubt that the gross(great) discrepancy of wealth distribution, though being a problem long existing in human society, is now developing to an extreme which may cause chaos. Therefore, the whole world should take this problem into serious consideration. Only through a systematic reform to achieve a more equal society can we prevent the problem from deteriorating.
