Outside of Zurich rentals are not even that bad. You can easily get a nice apartment for 1500.- or even less. If one is struggling financially, rents are lower e.g. in Aarau district, starting from around 1000 and you can commute from there. Spending 1000 when the median salary is around 7000 is really not that bad. Low inflation in Switzerland meant other European locations are now at the swiss level or sometimes even above.
