The cost of living is so much higher, that it is often necessary for there to be two incomes in the household. Prices have gone up a lot and in some cases incomes have also gone down and so one income is not always enough to cover the bills. Although the cost of childcare will have to be met, once children are at school, it is usually possible for these costs to be easily met by part of one income.
There is now an expectation that women have to work. Most people do not expect women to stay at home and look after the family, but they feel that they should be out working. The woman can feel under pressure to get a job and go out to work.
Partly due to the pressure on women to work, they may not feel good if they do not have a job. They may feel that they have any self-worth because they are only looking after their family and not contributing to society in an additional way.
People seem to need more things these days. They want all the latest technology, lots of holidays, toys for their children, lots of clothing and so on. This need for more and more things means that it is necessary for the extra money to be earned to pay for it all.
Since more women started working there have been fewer jobs to go around as there were more people in the workforce. This means that salaries have not been able to rise so highly and working hours are not so long. Therefore to keep a decent household income, both parents are forced to work.
It is possible for a family to manage on just one income. However, they would not be able to live the same lifestyle without having to turn to things like OnlinePaydayLoans.net for help. They would have to go without things, such as holidays and lots of gifts and may not be able to go out to visit places as often or buy the latest phones and tablets. However, they may feel that it is far more valuable for the children to be with a parent more often.
