Show gratitude for your job and a predictable cycle will occur. People value their job more when they’re grateful for it. When people value a job, they do it well. When they do it well, they get promoted and make more money. When they’re not grateful for their jobs, they don’t value them and don’t do them well. They then stay stuck in a job they hate, complain about how they aren’t paid enough to do the job, and whine about how they deserve more. You won’t be grateful for what you get in the future if you’re not grateful for what you have now.
