Robert Kiyosaki is right

I hope that I'm quoting it right:

The most important lesson we could learn from history, is that nobody learns from history

I his book "Rich dad, poor dad" Robert Kiyosaki has stated that the rich will always find a way to work the current situation to their benefit. One example that was given by him is the history of tax law. Before the twentieth century there was no general income tax in US. There were special taxes for specific reasons, like an for a specific war. Then people thought that making general tax will make the rich to pay for the people needs, but they were outsmarted. In fact most of the tax burden lays on the shoulders (and pockets) of the middle class, while the rich get richer.
Now, after a brief history lesson, I come to the main idea. The socialists made a variety of laws to protect the rights of the employees. Guess what? Right! They were outsmarted again. The manpower companies were introduced, allowing companies, even at considerable expense, to clear themselves from the responsibility toward the employees. Sounds familiar?
