Back in the day, robber-barons simply exploited the working class through substandard working conditions, and outright theft of money or property [citation needed].
Now, though, you need a deep understanding of global monetary policy, tax law, and labor laws to be able to connect the dots.
So I would argue that now is different from earlier times in history, because those who are exploiting the system have finally figured out how to a) hide it well enough, and b) co-op members of the classes being exploited to fight for those doing the exploiting through misdirection and propaganda.

Now some investors prefer buybacks for tax reasons, others may not. It depends entirely upon how they invest. If you're a buy-and-hold, then it's favorable due to lack of taxes, but if you rebalance a lot (which most mutual funds do), then it doesn't matter.
I don't think that is true at all.
A dividend is literally "We are paying out some amount of cash. If our stock price is $40 and we give $5 to each shareholder the shares should immediately go down to $35". Although since the stock price should be a NPV of the company's cash flow, they technically have even less working capital to create returns over the years, so I think the price should go down by even more than $5.. but that's a different discussion...
In a stock buyback.. let's say the price is $40 and they buy the equivalent of $5 back from the market. Well.. yes they gave away $5 but they also gained $5 of value because they are now holding the shares. It's a net zero transaction if their stock price doesn't change from it. Which.. it shouldn't unless you think it's a signal of something. Yes there's a bit more details, but value is not "given away" in the same sense.
In the dividend example, the company gave away money.
In a stock repurchase, they gave away money in return for shares of (almost) equal value.
I do agree with your sentiment though. I feel like the wealthy in this country have developed the perfect scheme for leeching the wealth from this country. We will only know how bad it was after the postmortem, at which point, we will be (figuratively) dead.
