Here is one other solution to the problem of an aging population in UK.
increasing age of retirement
Increasing the age of retirement is a controversial topic in the UK. It is hoped to rise from 60 to 65 years old between 2010 and 2020. Then, it will be a big bonus if it rises from 65 to 68 years between 2024 and 2046. The UK government is expected to introduce this in the near future, with the intention that the elderly can continue to contribute more to society instead of continuously depending on the shrinking workforce.
