It sounds sleazy because it is. Selling pipe dreams to dreamers without the ability to make it. Those people never learned or heard that if one does not make it on his own nobody can make them make it via shortcuts such as a few thousands in "education". A lie sold to fools who don't know better. Greed makes people do incredibly stupid things.
Those are such sleazy statements. "Making your own luck" means nothing. Luck is always external, that's just the definition of luck. If all it takes is a good firm to teach good methods, there would be so many trading millionaires as "working hard" is quite common, not a rare quality.
