Most of them definitely prefer a city, which in contrast to the suburbs gives (ale komu? musisz napisac) more opportunities (jakie? daj przyklady). I really understand and share their point of view, but I cannot agree with all THAT they claim.
Many students 'are aimed' (to jest zle, moze 'aim') developing their job careers, as well as living there after graduation.
Only too high (brak przedimka) price can constitute 'the' (chociaz ja dalabym 'a') barricade against the purchase.
Almost everywhere people 'meet' (nie, to jest za bardzo po polsku, 'spotykaja', ale po ang. to 'come across') many kinds of shops where they (mozna dodac modala) buy whatever they want. Last but not least, it is not worth forgetting about entertainments like cinemas or fitness clubs, which big cities offer 'us' (dlaczego piszesz 'nam' jak wczesniej mowiles o 'nich'?). It only depends on 'our' (nie, bo nie mowisz o sobie albo o mnie, tylko o nieznajomych ludziach) choice how to spend a free time nicely.
Their areas are free 'of' (ja wole 'from') car fumes and other harmful substances. Besides, lower number of vehicles 'reduces' (reduce) persistent noise, which (tutal mozna dodac slowo 'ultimately') affects people’s comfort in a positive way.
I strongly believe that it is better solution to live in the 'centre' (raz dajesz AmE spellings (np. labor) , a drugi raz BrE) of a city.
