It’s due to indirect representation (elected decision-makers, rather than democratic decisions). Lobbying is one mechanism for this, but it’s a symptom not a cause.

Strict majoritarianism is pretty ugly (“three wolves and a sheep voting on dinner”).

For a more concrete example than wolves and sheep, consider that narrow homosexual interests are beating broad homophobic interests.
