This is a huge problem even in the western world. Young university femail students have to pay their rent, food, electricity, transportation, clothes etc..... Students do get support from the government at least in the europe. However this isn´t enought! They start selling themselves. In UK, France and Finland it is actually very common today. There are even man prostitutes. If you don´t want to borrow money from the bank you haven´t got many options. You could always go to work but today it is more and more difficult to find work. You can earn between 50-400 euros from one sex customer/hour. For example in the UK you often have to pay tuition fees if you want to study. In Finland it is free but I´ll something for you:
University student budject in Finland
Goverment gives you every month 400-499 euros for free.
Pay these
rent: 300-600euros/month one bedroom apartment.
food: 150-270euros month
students also very often spend their evenings in the bar so even more money burns
electricity: about 33e/month
hygienic stuff: not every month but often 30e
Internet: 19-25 euros/month
phone bill: 10e if you don´t talk too much.
Bus: about 24e/month in helsinki elsewhere about 75euros/44 times(use)
Rent is very hight in the Helsinki. Lower rents can be found from small cities.
Hope you don´t need to use car. In Finland things are pretty good and there are many western countries where things are not this even this good.
