"Generate wealth" means "make somebody's number go up" i.e. allocating real resources/capital somewhere, with the assumption that 1. allocating that capital creates a net boon for society and 2. those who have "generated wealth" are wise and competent investors/leaders and their investments will create a net boon elsewhere. The first point is probably not especially true very often in contemporary tech (other than 'job creation') and is arguably not true for advertisement. The second point is not really a given at all and seems to be pretty consistently shown otherwise.
