Specifically a manned flight to mars, which before depended on the cyclic political will and state of the cold war to be funded. There are also other uses for starship like 30 minute suborbital flights between new york and london. Maybe it's easier to see if you look at the limits: given an infinite amount of money and labour, we wouldve seen a manned mars landing in the 1980's perhaps. If on the other hand funding was finite and reaching mars cost 100% of world gdp, it would never happen.
