english: But if growth slows down, instead of doubling our standard of living every generation, Americans in the future can't expect to be twice as well off as their parents, or even a quarter [more well off than] their parents.
non_english: Ali ako se rast uspori, umesto udvostručenja životnog standarda svake generacije, u budućnosti Amerikanci ne mogu očekivati da žive duplo bolje od svojih roditelja niti čak četvrtinu bolje od svojih roditelja.
