Well, I think it is instructive to first understand that the Federal Reserve is NOT a government organization.
It is often called a "quasi-gov't" organization, due to the fact that it has an appointed chief of its Board of Governors, and it "reports" to the Congress once a year, and that is called "oversight".
The Federal Reserve has NEVER been audited to verify what it reports.
What the Federal Reserve actually is, amounts to a private cartel of bankers, who own privately-owned banks and have shareholders, They are a private business entity, which could fall under the rubric of "big business".
What they have is a gov't-granted monopoly on the money and monetary policy of the USA. This allows a private group of bankers to dictate exactly what the US money supply and policies will be.
To make matters worse, they have implemented a fiat-currency, and have left the realm of sound money. And they have instituted a "fractional reserve" system,which allows them to lend 10x more money than they have, in order to make more interest profits. Since interest payments is their main profit, they are inclined to make as many loans as possible, and strive to loan out as much of that 10x more than they have, to maximize their profit potentials. And, since they are in direct control of every dollar that comes into the money supply, and make interest profit off of every dollar that comes into the money supply, they are in the position to make money from the entire US money supply, just by virtue of having that monopoly. Every single dollar that is printed or computer-generated in ledgers, every single dollar in this nation has an interest debt attached to it. It's called the "Fed Rate". You "buy" dollars from them with an interest payment automatically attached to it. There are NO dollars which aren't loaned into existence with debt attached. NONE.
So, we now see that this isn't a "gov't agency" at all.
We see that this is a private banking cartel that has been granted an exclusive monopoly on ALL money in the USA.
They might claim to have "gov't oversight", but no oversight actually occurs. No audits occur. They generate the inflation that we see every year, all by themselves, by increasing the money supply to further increase their profit taking by interest charges.
Except they loan money that they don't have, so they don't have to have the money to loan. They just create the money out of thin air, and loan it out by their "fractional reserve" methods. This allows them to generate huge interest sums from money they don't even have.
And the money is "backed" by the "full faith and credit of the USA" , so that if they fail, they aren't on the hook for anything, but the people are.
The entire thing is a scam, and the original Federal Reserve was created and is still presently owned and operated by the very people that you seem to be concerned about. Rockefeller, Morgan, Schiff, Loeb, Lehman, etc.
ALL of these people were/are the "robber barons" that made up the late 19th century magnates that oppressed labor, as you like to point out.
So, I find it interesting that you might see virtue in these "robber barons" owning a private monopoly on the US monetary system.
A money system which was originally founded on sound money that can't be inflated, and wasn't generating interest profits to monopoly bankers, and the authority to "delegate" that monetary power to a group of private banking tycoons was NOT granted to Congress by the Constitution.
