They want to have (brak cos) better future
They spend less time with family because each of them 'have' (ale to ma sie zgadzac z 'each')responsibilities.
Young people 'dot' (co to jest?) have money for a ticket so they can't visit 'Their' (mala litera) family. Family realtionships become difficult and 'They miss for each of loved ones' (tego nie rozumiem). People who moved to 'another' (zle slowo) countries can earn more money and learn many new things for example about (tutaj ja cos dodalabym) culture.
