I'd put moral flexibility above hard work, personally. Usually being morally flexible leads to doing less work and lying/cheating about said work wherever possible.
I still think pure luck is up there as well, maybe near intelligence. Not only do the pieces of an opportunity have to align at the right place and time, you have to be aware of them and take the opportunity (the intelligence aspect)... or fumble your way into it out of luck because the opportunity was imperceptible to mere mortals.
One of my old directors played moral gymnastics with everything and was making out like a bandit doing virtually nothing.
It doesn't matter if an action is moral or amoral if you're too lazy to do it.
And while the top comment isn't wrong, it's hard to overstate the foot-dragging mentality and general "laziness" (for lack of a better word) of much of the workforce, in that they seem hardwired to make any excuse to avoid a difficult task assigned to them.
My test for this, especially with younger workers, is to ask them to lookup some information that seemingly would be on the internet, but isn't. Do they give up after a couple of web searches, do they email and wait for a response, or do they pick up the phone and try to talk to somebody right now.
There's no shortage of questionable business practices out there, but don't discount the average persons lack of ambition.
