The consuming habits of the baby boomers (those born between 1945 and 1960) have substantially eroded the rate of saving in advanced nations over the past 40 years. Spending up rather than saving up has created an untenable situation. And future generations will almost certainly have a lower standard of living, unless policymakers step in to reverse the trend, according to a new study from the Australian School of Business. With an ageing population accelerating the problem, researchers suggest the "I want it now!" boomers should curb their selfishness and consider the kids.
