The difference between loyalty and taking advantage of people is directions.
If you demand loyalty from others but don’t give loyalty back to others, that isn’t loyalty, that is taking advantage of people.
If you give and take to the same extent, that is loyalty because it goes both ways.
One sided loyalty isn’t loyalty. If you aren’t willing to do for others what you are expecting them to do for you, that isn’t loyalty.
Loyalty is a word thrown around a lot but rarely honored the way it should be.
Have a great day!
