Filmmakers and writers use shipwrecks as a literary device to make a point about social inequality and to sweep away all traces of privilege and social convention. Wealth ensures a comfortable lifestyle and political influence. But by dividing society into the poorest fifth, the second poorest fifth, the middle fifth, the second-richest fifth, and the richest fifth, the winners are the richest families. In terms of wealth, the rich are getting richer and the poor are getting poorer. Income is the amount of money earned in a given period. Canadians earn more now than they did before, but that"s because they"re more productive due to the advance of technology and mostly because of inflation. We have to divide the population by income: the top 20% of families and unattached individuals, the second 20%, the middle 20%, and so on. The distribution of income has become smaller. The richest fifth canadians lose about a fifth of their income to income taxes.
