At the moment, the current generation of wage earners is having to pay for the welfare of their parents, and also make provision for their own old age as there is no guaruntee that the next generation will be able to support them.
Add to this that this current group of wage earners is also being asked to fund ever more consumer oriented lifestyles for their young, and it is pretty obvious why the birthrate is declining.
One group of wage earners is effectively having to support three demographics, and since the changes in pension funds, from underperformance to rules changes, it looks like these will probably have to work longer, in th UK women retired at age 60 and men at 65, but this is seen as sexist, so the ages ware going to be equalised, no prizes for guessing which way.
0n top of this, some workers have appaerently been to law to ensure they have the ‘right’ to work beyond normal retirement age.
This is of course only a personal choice, you understand, and I note that those who state they want to work so late in life tend to have very much less arduous work than the blue collar workers, and have generally enjoyed a greater income, yet it is the presedents they are setting that will ensure that the rest of us will have a ‘choice’ of living elderly in poverty, or working until we drop dead.
Oddly enough, more houses are needed, as the average household size has also decreased, where once it was usual for four people to live in one house, now it is more normal to have three, and the number of single people is also increasing.
This means that despite a falling population, there is need for ever more housing on this already overcrowded island of the UK.
