I find it amusing how they still use this dated 1970s language about saving "free enterprise" - as if the NDP under Horgan or Eby ever posed the slightest threat to free enterprise. Its not as if the BC NDP has workers of the world unite as its mission statement and wants to nationalize all heavy industry.
I understood "free-enterprise coalition" to just be the colloquial term for the anti NDP alliance of Liberals and Tories in BC. I'm pretty sure it's just useful shorthand carried over from the NDP vs Social Credit era when the NDP did in many ways pose a threat to business. The BC Liberals/BC United even presented themselves as a "free enterprise coalition," so it can't imagine that exactly harmed the idea of continuing to use that phrasing.
