Greta Thunberg: ~ $1 Million

Looking at the unassuming teen climate activist Greta Thunberg, it may not be apparent that she is such a positive influence on the youth of the world. She is working hard to make the world aware of the terrible effects of climate change.

Since 2018, when she first gained recognition Greta has made at least $1 million, as per media reports. She won a prize of €1 million, after being awarded the Gulbenkian Prize for Humanity, which she donated to charity. Greta lives a humble life in her family’s home, and is seen in eco-friendly electric vehicles.

Billie Eilish: ~ $8 Million

One is inclined to think that millionaire songstress known of her hits Bad Guy and Ocean Eyes, Billie Eilish may live in a huge mansion, but that is not the case. The 18-year-old has made a huge name for herself in the music scene in a relatively short amount of time but she still lives with her parents.

That’s right, this modest 2-bedroom family home is where Billie lives when she is not touring for her concerts. She may think it’s time to move out though! The young singer is known for being humble and down-to-earth and although she poses in front of muscle cars for her social media fans, she actually drives around a rather simple black vehicle.
