Interest on loans is tax-deductible. Any businessman faces choices of investing in X, Y, Z, or leaving his resources in the safety of government bonds. Patents, copyrights, and other protections of property support such investments. I don't know. The reality is that many publishing companies run in the red and authors' contributions to their copyrighted work far exceeds the income derived.
Many properties end up as remainders or shredded paper.
Given the importance of the copyright industries to education, science, social, and cultural interests, I believe investors should have every encouragement possible under protection of law. Only if you will defend the criminals. The IT companies I mentioned depend on patent rights to sustain high prices and enormous profits.
