A person’s first instinct when they lose their job is to find a new one right away. But it wouldn’t hurt to take a few time off and reflect why you lost the job. Maybe there’s something you lack. Maybe there’s something you can improve. Maybe you can invest in yourself more and learn new things. Learn new skill sets. Explore and experience new more things that could help you land a better and more stable job in the future.
Unfortunately not everyone has the privilege to not work and focus on themselves that’s why they never improve in terms of the job they land on. Since they don’t have the time to focus on themselves and their skills, they remain only on a specific level and their wages are also the same.
You have mentioned it because everyone lives in different countries with different incomes, so not everyone who works hard gets a commensurate income, so when they lose their jobs they can only think about finding a new job.
But you don't have to wait until you lose your job to do self-evaluation, but while you are still working you can do it, self-reflection needs to be done whenever you feel there is no development in yourself, that is a good time to do self-reflection.
Unemployment is a really big problem, and the even bigger problem is that many people do not want to solve it globally, and every time they lose a job, they look for another one for a long time, experiencing great difficulties in the meantime. The other side of the problem is that most people from the “risk zone” never think about ways to solve the problem by starting their own business or changing their profession globally.... And that could solve their problems. But it is more difficult than looking for a new job “for pennies”.
