This is a common misconception I've seen everywhere.
You don't need to be rich or famous or have anything of value to be hacked or be victim of identity theft. First there are random hacks, to literally anyone that can fall prey (much like a random robbery on the streets), the more the better, no matter who the target is.
A stolen identity can be used to commit crimes on your name (instead of on criminal's name) or to take loans on you or buy things using your name, those all have already happened. A hacked computer can be used to direct attacks, becoming part of a botnet or to mine bitcoins using your hardware and electricity. All those don't need you to be particularly important.
You can even be targeted specifically for you even if you're not important. Well, you're important for someone, for example a disgruntled partner, a family member, an employee/employer, there are many ways you can be of interest to someone, without the need to be rich or famous.
Definitely the "I'm not important, I won't be hacked" motto doesn't holds on the real world.
But I generally agree on the thing that most street roberies aren't for the sake of data stealing but for reselling whatever you happen to have on you at the time.
