Actually what you say is probably what you believe to be true, but it is not: in Western Europe there is a safety net, but it does not work that simple so you work and take a break, with such a work history you can't get any credit to buy a house or a car or anything more that what you can afford in cash, not even an above average smartphone. The safety net works if you lose your job, not if you quit when you want a long vacation. In some countries the money you get are very close to the minimum wage, in others the difference is big enough that you want to work to have some money to get out with the friends once a week.
