My pleasure. The best books analyzing the current crisis of capitalism, and based in the teachings of Marxism, are Fred Goldstein’s “Low-Wage Capitalism” and “Capitalism at a Dead End.” Both of these books are available to read and download free online.
For a crash-course on capitalism in the Marxist classics, I’d recommend Karl Marx’s “Wage Labor and Capital” and V.I. Lenin’s “Imperialism, the Highest Stage of Capitalism.”
And also Steinbeck’s The Grapes of Wrath!
