Your 'working life' = a term used to try to persuade you that it's somehow normal to spend 40 hours per week for 50 years in a shit job.
Why do people stay in jobs that make them miserable? I've done it myself at times, and the main reason I can think of is keeping a roof over my head, and in more recent times doing the same for my family. Depending where in the UK you live and whose figures you believe the average house currently costs between six and ten times the average wage. Hang on though, that's between six and ten years of gross income, so after tax it's more like somewhere between eight and twelve years. Then there's the interest, which still runs into hundreds of pounds per month, even in this period of record low interest rates. You have to pay the bills too and, well . . . live. So without being able to save any money the average person in the UK can just about keep up with the average mortgage, spending everything they have to keep a roof over their heads and they will have it paid off in about twenty-five to thirty years, and that is why mortgage terms are twenty-five to thirty years generally, so that the banks can bleed you white for the greater part of your working life. And remember "you risk losing your home if you don't keep up repayments."
Wages are currently just about static, so all of the above holds true for the average. However, anyone finding themselves earning more is encouraged, often for reasons of status within society, to 'move up' to a larger property, taking on more debt in the process. Perfectly good homes are described as 'ideal for the first time buyer' or 'starter homes', insinuating that you shouldn't be planning to stay in them for too long if you are on your way up in the world.
The reasons for this blog. Imagine if you didn't have to pay that mortgage or the rent. You could choose to work part-time, or save for a while then take a year or more off when you felt like it. The fact that ordinary people who do that are sometimes described as lazy gives you an idea of how deeply ingrained the 'working life' mindset is.
