"Bez chytrých studentů lepší budoucnost nebude."

Translation: Without smart students, there won't be a better future.

Why is "There will not be a better future without smart students" wrong?

[walkinwolk]

How did the spelling of "budoucnost" get a "c" before the n instead of an "st"? Yes I know this is correct, but it seems unusual for Czech.

[VladaFu]

Because it is how it is pronounced. It is pronounced "c", not any "st" or "ts" or anything like that. Etymologically it is derived from the adjective budoucí = future.

Also, there is nothing unusual about that. Adjective ending with -cí or -cný -> noun ending with -cnost. Mocno(st), jsoucno, vroucno(st), you can basically many random new words like this from any such adjective. The meaning is often quite abstract.
