Perhaps YOU need to re-read it. "Going Galt" means to sabotage then walk away from your business. You instantly become a wanted man, so you'd better have a hidden "Gulch" to retreat to.
Not really. Galt sabotaged his engine and many of the key industrialists sabotaged their business (because as corporations, the business would go on without them), but most just disappeared without a trace leaving people wondering what happened to them. If they had all publicly destroyed their business, no one would have been wondering.
I need to rereread it, too, lol! I thought it meant to allow means of productivity to slowly circle the drain and go down without an attempt at saving it.
Sorry - no it doesn't. While Francisco D. & Ellis Wyatt did willfully destroy their businesses, the rest either walked away - or in the case of John Galt - persuaded others to walk away.
In fact Midas M. did just the opposite of destroying his business; on the day he left, deposits were returned. The looters hoping to find some pickings instead found his books balanced to the penny. Nothing remained, but none of his depositors lost a thing.
Francisco's rationale for willfully destroying his business was that the nature of mining would have allowed slave labor to exploit his holdings for a century or more - even in his absence.
Ellis? He was just grumpy...
