Science is an ideal, the pursuit for knowledge for its own sake. Science is a boon for humanity because it provides an unparalleled degree of prediction and control of the natural world.
But it doesn't tell you what to do with that.
A "capitalist" will seek personal, short-sighted gain from it, socializing repercussions, no matter how devastating. They will gladly poison society and the planet and sell it to you as "your own fault". Their life-span is limited still, so what do they care?
Technological capability exceeding human wisdom is the core issue here.
You need scientific understanding on your own side in order to know and judge the alternatives beyond what vested interests feel obliged to tell you.
