If you'd like to better understand the transition from Marx's critique of capitalism to Baudrillard's, watch these two comedy sketches respectively:
Mr. Show's "The Fairsley Difference" (https://youtu.be/tP4yX2rkpBc)
and Tim & Eric Awesome Show's "Prices" (https://youtu.be/hJ9yBgTp9UQ).
Mr. Show relies on classically anti-capitalist themes: monopoly, false advertising, how small firms are driven out-of-business by corporate chain-stores; prices are still based here on real production and real competition. (There's even a Foucauldian angle to the adoption of surveillance security.) In Tim & Eric's postmodern capitalism, however, prices become pure simulacra entirely disconnected from the real economy. (There's even a Nietzschean angle to accelerating the system to its own destruction.)
