Nonsense. Capitalism has been a constant generator of new ideas. That's one of the reasons capitalism is so successful: it gives the green light to innovation, and in fact to as many innovators as possible. This is in direct contrast to the sclerotic, new-idea-strangling milieu of the "command economy."
Socialism is an old, stiff, enfeebled ideology whose time has passed. It smells of mothballs, of the 19th-to-mid-20th century.
