Okay so maybe I'm just looking too far into things (I tend to do that a lot), but I feel like this song is about more than just not having any money. To me, this song is about starting from the bottom and making your way to the top. The music video in the beginning shows Calum, Mikey, Luke, and Ashton all having crappy jobs that they hate, but they have to work otherwise they won't have any money. I see this as a metaphor for when they were first starting out and they had so many people telling them they'd never make it. But, they kept on dreaming about that one day when they would hopefully get discovered, just like in the video how they're dreaming about what it would be like if they had tons of money and didn't have to work. Then, at the end, they're all doing the jobs they want and they don't have to worry about money anymore because they worked hard enough to earn the higher paying jobs. Now, 5sos doesn't have to worry about the people who said they couldn't do it, because through hard work and dedication, they've already proven them wrong. Again, I could just be looking for a deeper meaning here, but that's what it means to me.
