But that is not the point. The point is, that the manual labor gets less and less earnings, but the possession of the properties. How many creative products with high value are in the hands of their creators?
In reality, the high earnings are not made by the inventors or creators of things, but by those that have acquired them in any way. In corporations, it is normal, that inventors just get some small fixed amounts for their inventions. Even in the music business, the musicians have the smallest part of the earnings. Often time, the musicians have to sell the rights to the companies, so the companies are earning most of the money. Only very few musicians can make extra-deals and get rich.
To answer your second question: No, it is absolutely not the intent! By making "intellectual property" the same level as other property, the intent is not, that the inventors should have them (as normal copyright once was intended), but the intention is, that it is a trade-able good, that can be accumulated by the wealthy and used against those that are creative (something, that money is not, so creativity must kept cheap).
