I get what you are saying but the same thing happens everywhere, even in other industries. A friend of mine works for company, a few years ago, before the pandemic, they were hiring new workers at about the same salary my friend was making, he had been there almost 10 years. He decided to stick around but other workers who had been there a while, left because they didn't think it was fair. Is it fair? No but it's all about the market and what a company and it's competitors are willing to pay.
I do agree that workers who had been with Macy's for quite a while, should get a bump in their pay, especially now that Macy's is willing to pay more for new hires. I don't think it's fair for new hires to make as much as someone who has been there for 5, 10+ years, but you have to understand that this past year was not the norm, outside forces like the pandemic and other things, played a big part on wages. As you can see, even with higher wages, some people aren't willing to work or not willing to go to work, so companies had to offer more money to get new hires.
For your part, talk to your people leader about it, if they value you, maybe they can give you a bump in pay, if not, then do your job as best as you can while looking for something else, other companies are paying more also, so use your experience and leverage.
