ratio of wage-hikesとは 意味・読み方・使い方

But a host of problems remain regarding such insurance. First, insurance premiums deposited with a fund are short as the ratio of active workers per one retired worker declined to 3 from 5 at the end of the 1980s.(Fiscal deficits are expanding while contributions from the fund are increasing) The second problem is money not being sent to individual accounts set up for the fund. Third, investment of money deposited with the fund is confined to government bonds and bank deposits, making it difficult to ensure investment returns that surpass hikes of prices and wage increases. Because of these problems, insurance subscribers are not completely free from concern.例文帳に追加
