"There's this tendency in the welfare state to sort of outsource the elderly care," Jan-Emmanuel De Neve, director of the Wellbeing Research Centre at Oxford University told CNBC Make It.
Although home-care for the elderly improves their wellbeing, it can also place pressure on younger generations.
The so-called sandwich generation refers to middle-aged people who have elderly parents to care for, as well as their own children who are still dependent on them.
The younger generations have to support their elderly parents or grandparents.
"This would entail defining one's family value system, setting out personal goals, life aspirations, allocating and committing personal resources," Wong suggested.
