I feel like this verse has a much deeper meaning... This can totally apply to things like climate change, We are stealing from future generations their habitable environment. It's not like that the Rich don't steal from poor, We have countless examples where this has happened.
There is not a simple answer to your question TBH. One can argue it was written by a rich person to ensure his Power/Wealth remains in his control, but we didn't have a democratic system back then. It was a literal "Free" world. One could kill you and take your stuff. So the word "stealing" doesn't make much sense. The verse could have been something like Do not "kill" others for your gains. Stealing is a lighter word in this scenario.
"There is a big difference here, and most rich people get where they are by stealing profit from their employees. Profit is really just unpaid value that workers created so they are taking back what was taken from them."
The only issue I have with People nowadays is that they believe the capitalist society is the only answer to the modern world. They aren't open to new ideas and if you suggest an alternative, those in power come crashing down on you along with their zombies which have been mass-produced under their "System".
If you look carefully, religions make sure that the poor stay poor.
Care to explain how? An example would be great...
