I cannot say at this time if I think it is a good thing to impose, but I do say that it is a fair proposition.
- High salary / comp packages can be disbursed in such a way that just-taxation is tricky
- Such a ratio is indicative of significant profits (i.e. such salaries are global market-rate, not subjective)
- Corporations acting at this scale can be difficult to regulate or otherwise control, when their acts begin to exceed the history of legal contemplation.
Since these corporations are globally-impacting, their top-earners can domicile elsewhere, or can relocate their base of operations elsewhere... regardless of where top executives live.
Such a law cannot effectively be enacted without national or global transparency on changes in corporate structure, salaries, etc, that would happen after the effective-date of such legislation. At this time I would not be sure of the benefit of such legislation without also including such reporting / transparency mechanisms.
The responsibility of such reporting would fall to a California government office, since the corporate filings of those natures are already regulated by law under the SEC.
Also, this vote and discussion should link to the text of the bill, not to an opinion-piece article.
