What does Jesus mean that those that can be trusted on small matters can be trusted in large matter?

Imagine Madoff coming to your living room and saying, "I got an investment that I want you to invest all your money in." You test him. You left some changes on the table and pretend to do something else. You return and see the changes are still there. Ah I can trust Madoff in small things. He must be trustworthy on big things. That would be stupid, right? Many people don't steal small things not because they're infinitely trustworthy. People don't steal small things, so that they have their reputation intact and can steal big things. Madoff didn't take the change not because he is trustworthy. Madoff didn't take the change because the change is small. He aims to steal big. So those who are trustworthy on small things are not necessarily trustworthy on big things. I once lost $30k due to a fraudster that built trust by being honest on small deals. When the deals got big they ran away. Likewise, most corrupt officials that steal billions won't steal chickens or bread. On then face of it, this appears to contradict some of Jesus teaching on trust: >[Luke 16:10](http://biblehub.com/luke/16-10.htm)
> "Whoever can be trusted with very little can also be trusted with > much, and whoever is dishonest with very little will also be dishonest > with much. How is this apparent contradiction resolved? Note: I honestly trusted this interpretation on Jesus words and lost almost $1 million of profit because my ex-employee become my competitor. Consider this a form of "customer complaint" on Christianity.
