"When the Sony hack happened and I found out how much less I was being paid than the lucky people with dicks, I didn’t get mad at Sony. I got mad at myself. I failed as a negotiator because I gave up early."
Wages arise from capital. Where there is no capital, you never find wages (parts of Africa). Where there is high capital per worker, you find high wages (surgeons). Where capital is lower per worker, there are low wages (China, India) [See: SOPHIE'S CHOICE OF CAPITAL OR LABOR. A FREE-MARKETS LIBERTARIAN BECOMES AN ANTI-CAPITALIST AND PERPETUATES AN ECONOMICS MYTH].
Every movie print distributed is capital. When a movie print gets shown, a movie showing becomes wealth sold for the wealth in cash or other bank credit in such purchases and sales.
Where there are more copies of the same movie distributed, there is more capital supporting more showings.
Among the world of movie goers, consumer preferences expressed in sales of cash or other bank credit for movie showings reveal some kinds of movies sell better than others. Those movies have more prints distributed (capital) and to the contractors (actors) who produce the work of those movies get higher payouts.
Jennifer Lawrence earns substantially more than Steve Buschemi or a
James McAvoy precisely because distributors can make and sell more prints (capital) of the same Lawrence movie over a Buschemi or McAvoy movie. Yet, no one seems bothered by that reality.
In addition to more prints, those movies that have the highest sales worldwide, typically take more capital (special effects, the work of technicians, specialized cameras) to produce. Hence earnings are higher across the board for contractors (actors) in those movies.
Worldwide, owing to biologically-driven culture — codified laws, codes of conduct — the law of averages reveals that male and female movie goers prefer seeing men doing the action of movies. Subsequently, actors get more screen time and dialogue time than actresses. Thus, actors are producing more capital each movie relative to actresses.
There is no conspiracy whatsoever why actors earn more than actresses on average. Why Jennifer Lawrence doesn't understand these matters likely is why she works an actress and not an investment banker.
Between August 2014 and August 2015, Lawrence, the 25-year-old Hunger Games actress banked $52 million pre-tax over 12 months to be the best paid actress. Lawrence earned $16.5 million more than second-ranked Scarlett Johansson ($35.5 million) precisely because Lawrence's movies had wider distribution (more capital).
Likely, Lawrence would never acknowledge she earns much more than most actresses and actors for that matter precisely because she is one of the lucky people with pretty faces and one of the lucky people with relatively fit bodies.
