In the article it mentioned she made 100/month as intern. You can make more money working at McDonalds. It must not have been the US. I think developers in the US have it pretty good.
In 2017 Germany I made net ~570€/month (~1€ more than minimum wage) working 15h weeks in a supermarket for around 3-4 months while studying. It was pretty mindless work (apart from always looking out for the use-/sell-by dates) and also nice working in a colder part (dairy and frozen products) of the supermarket during the hotter months.
