Because for many employers, they live under the false pretense that not giving you a raise is saving them money. Granted, it works most if the time. Most people stick around out of complacency or even inability to get a new job. This makes it so that the employer has absolutely no incentive to proactively give raises. You really must force their hands. This is why I don't believe in the stigma around job hopping. It makes no sense why anyone believes that being loyal to a company is in their best interest. Every 2-3 years make sure you are putting yourself on the market to test how much you're worth.
