Why? If you are an actor on Broadway, your minimum pay is $1,861 per week[0]. So if you're working 40 weeks per year, you'd be making, as a minimum, $74,000. This is higher than many teachers' salaries, and in line with many other professionals. Plus there's a very high (if very narrow) ceiling on those salaries.
You can make the argument "well most actors never make it as a broadway actor". While true, do most software developers make it as a Google developer? And how likely is it that someone whose talent lies in acting is also talented enough to do well at software development? Sometimes, you should play to your strengths, even if the relative bargaining power of your strengths are not as strong as someone else's strengths. That doesn't mean you're not following the best path to "have a better life".
