When we put our trust in another, the burden is on us.

I have noticed this is the case in middle class and lower class. I have never seen rich people putting the key to happiness, stability and wealth on other person. If the person stays or goes they don't bother with it. I suppose trust is the component when you are vulnerable. When you are rich or powerful, people are not worth trusting because you have to hold onto mantle as it is. And trust is less likely to convert too. Just my observation :)
