Capitalism, Socialism and Democracy

"Creative destruction" in its original formulation — and the book is much broader and stranger than the phrase it spawned. Schumpeter's argument is that capitalism's defining feature is not price competition within stable industries but the periodic destruction of entire industries by new ones. The entrepreneur is not an optimiser but a disruptor of equilibrium, and the process is inherently violent to incumbents. Without Schumpeter it is hard to read Christensen, Carlota Pérez, or any serious discussion of why industries die and are born. For product people the implication is structural: the game is not to win within the current frame but to recognise when the frame itself is shifting. Read at least Part II, where the core economic argument lives.
