It is (was) not in the interest of the rich to destroy the planet, but so long as classes are pitted against each other that war mentality prevents either side from clear thinking and from seeking to fix the system for everyone, which is the only (faint) hope we have, because a real socialist revolution will be much too late at the rate things are going.
Justice may be less important than survival, but they are connected in many ways. The mentality of both sides in the class war must be transformed so we can try to make the system work for everyone. Taking sides, defending the interests of one's group, and demanding justice prevents us from moving forward and taking the most basic first steps to design a functional economy.
The claim that labor creates wealth, or the claim that business creates wealth, are examples of class propaganda designed to defend one group against the other. In a functional economy unearned income and inheritance would play central roles, but the workers just want jobs. The hatred of unearned income and inheritance blinds the left, because they associate those kinds of income with the evil rich. The rich are very happy that the victims of their propaganda don't want any unearned income.
We are all parrots even when we try not to be. Blame the old social construction of reality, aided by the new propaganda construction of reality ... if there is any difference beyond intent.
The rich think that justice is freedom from any taxation. The poor (at least Marxists) think justice is freedom from any profits taken from their wages. The revolution will be too late to prevent the results of that impasse. Meanwhile, the suffering and destruction continue. The greatest injustice will be the suffering of future generations. That generational injustice will go on and on because of what we are doing in this one destructive generation, fighting over what could be enough for all. Future generations will hate us, both the rich and the poor of us, when looking back on this harmful, not useful, benighted age that some people imagine to be utilitarian. At least, we are efficient at the useful and profitable (for us) destruction of our inheritance.
