Defined-benefit pension schemes are a problem because now, with the baby-boomers retiring, we're finding that we can't afford it. Many people can expect to live to 100 - that's 35 years of retirement after 45 years of employment when their employer probably only set-aside 10-15% of an employee's income for investment in the pension when it should have been 25-30% - so now the younger generations are paying for it - by using revenue generated from their activities to pay for the defined-benefit schemes which cuts into their salaries - and making them work longer years to make up for their own contributions.
