Bad ideas can kill people, leave them in poverty and impede human progress.
Good ideas can enrich humanity physically and spiritually.
Our human drive to work can only really be satisfied if we channel it into pursuits about which we feel strongly. In reality the demise of the ideas underpinning socialist economic thought was a process rather than an event. The explosion in financial services growth in the late 20th century and the economic activity which it serves signals the end of more than 100 years of ideological battle between the many disciples of Marx on the one hand, and believers in markets on the other. The lesson I take from this is that ideas matter enormously. Bad ideas can kill people, leave them in poverty and impede human progress.
