‘Structural change’

‘Individual gestures are futile, what’s needed is structural change.’ The great cop-out of the well-to-do lefty.

Suppose a man is caught in Thailand having sex with a thirteen-year-old boy. In his defence he says he agrees completely that the whole underage sex tourism industry is wrong, but there’s no point in him personally changing his behaviour because the industry is going to continue whatever he does, and what’s needed is structural change. Convincing?
