>> the people at the top of our economic system make money by doing basically nothing other than loaning out their money.
Hold on, buddy. Let's take a simpler case: that of a surplus. Suppose you earn $10 but you only spend $9. You now have a $1 surplus. If you do this ten times, you'd have a $10 surplus in your bank. You could then live one pay cycle without income or "doing nothing" as you put it. That doesn't make you "evil", that makes you prudent. You've earned that right... much more so than someone who spent $11, earned $10, and now needs a bailout from someone else.
When you come in and look at this after the fact and say, "look at that rich bastard, sitting on his ass", you're really deeply twisting the situation by not examining how we got there in the first place.
If you take away the ability for people to earn, keep, and invest a surplus, you take away the incentive to produce anything beyond what you personally need in the near term. Production is the foundation of wealth. All of these dollar bills mean nothing without it.
You're so focused on "haves" and "have nots". But how did the haves get to have? That's the important question. Most of us earned it through honest means: building and selling products and services to others who needed them.
To read your post is to believe that anyone who ever built anything is a thief, and anyone who ever didn't build anything is a hero. Isn't precisely the opposite true? Shouldn't we be celebrating people who built the goods and services we rely on?
Except that's not how it works. The "haves" earn $10, but receive income of $3000 by making sure other people who earned $10 only receive income of $9. Then everyone has roughly the same $11 cost, but the "haves" have a $2989 surplus and the "have nots" have a $1 debt. Further the surplus is then given to children of the "haves" who earned $0, but start with surpluses undreamed of by the "have nots".
That's extreme income inequality, and that's what people are complaining about. The person pulling themselves up by their bootstraps to become one of the "haves" is almost but not quite mythical. Most people that are thought of being in that category had backing that a "have not" doesn't have access to.
