答案                             Aging Problems
    UN has claimed that the number of people on the globe / should as expected reach 9. 2 billion in 2050, / which will include elderly persons numbering 1 billion. / One of the surprises is that / population growth is most concentrated in the 60 plus age group, / which is expected almost to triple. / Whilst many regard the aging of the population as a triumph of a civilized and caring society, / others see it as a major problem facing the community. / The increasing aging population will cause the increase in the dependency ratio. / This means that there will be more people claiming benefits such as state pensions, / and less people working and paying income taxes. / Thus, those in work will have to pay higher taxes. / This could create disincentives to work and for firms to invest, / therefore there could be a fall in productivity growth. / The shortage of workers could push up wages, causing wage inflation.
