"Read it and weep, you tax-avoiding leaner, you."

I read it and chuckled,  probably because Mason, A former member of the Trotskyist Workers Power group,  has somewhat Marxist views. In fact, his approach  (dream) could be summed up with....."it’s time to be utopian".

Utopia: " an imagined place or state of things in which everything is perfect"

I imagine Mason's utopia is somewhat illusionary, and that of the mine protestors lacking in facts.
