I think it is not so much suicidal as it is indifferent.<quoted text>
Capitalism has only the one purpose to create superprofits and this in a nuclear Society is suicidal.
The people at the top, are >>only<< interested in getting even more money-- that much you are spot-on about.
The problem is, they don't seem to care about futures, beyond their own short and petty lives.
And that leads to short-sighted choices that have long-term and dangerous consequences.
