That's not how capitalism works. If you make a new widget for $4.50 and sell it for $5.00 then both the buyer and seller are enriched. You haven't impoverished anyone.
You're reacting to the word impoverished. You have "extracted 50 cents from them," is that better? I'll change it. Don't get distracted.
Edit: Also, there's short-term and long-term enrichment. The widget I sell might be a capital good that earns an income for its buyer, or it might just as easily be something that only depreciates or even destroys other wealth. Whereas the money I've collected can reliably be made to earn an income in any number of ways, which is why I always argue that the money is usually inherently worth more, and nobody on HN seems to agree with that.
