No one objected to the Exemplar Plan. No one had the guts to do so. Ves had signalled very clearly that he was passionate about the profit-sharing scheme.
This meant that criticizing the Exemplar Plan implicitly translated to an attack on Ves! As long as the assistants weren't crazy, they wouldn't take the initiative to piss off their boss.
Though Ves felt dirty for resorting to such a coercive psychological trick, he liked the alternative even less.
As long as his mech designers mounted a serious challenge to the Exemplar Plan, then Ves would not be able to hold the high ground anymore. The illusion he weaved in their minds might shatter as long as someone pointed out the flaws.
The stories he crafted about benevolently investing in the clan and that earning money wasn't important to them were just excuses designed to stop them from demanding more money or shares!
