Making sushi can also help all of humanity. Elon Musk's SpaceX has added sushi chef positions, requiring a high school diploma, over three years of restaurant experience, and a series of physical fitness requirements. The hourly wage is $32.50 to $35, averaging around $7,000 to $8,000 per month. However, the downside is that only those with a U.S. green card or citizenship can apply.
