I do find it slightly weird that Paul Mattick (1969–) now seems to have dropped "Jr." from his name, making him fully homonymous with his own father, the legendary Paul Mattick (1904–1981), particularly as Mattick the younger tends to draw heavily on Mattick the elder; in the footnotes of the former you'll find frequent references to the latter, yet without any mentioning that they are in fact different persons. It makes you suspect that the son does simply agree with his father on everything (or at least on everything that pertains to the Marxian critique of political economy), which is indeed not only possible, but even reasonable. Now, will the third-gen Paul Mattick please stand up?
