while youre not wrong that companies hold a lot of the cards, forcing a range in a job posting dosent necessarily solve anything. in states where this has become law, many now just say the range is "$1 - $200,000" (or whatever)

the reality too is that a high value candidate who knows their market worth can probably demand ABOVE what a company would otherwise be willing to post/pay. wheras a more inexperienced person who they see promise in they may be willing to take a chance on, but for a lesser salary. theres also no way to account someone whos under-performing in a role and not getting regular raises and is on the lower end of the salary band vs someone who is killing it and is getting tons of offers and who the employer is desperately trying to hang on to because theyre critical to client success. i guess what im saying is, a role can say its "range" is $100k-150k, but ultimately a good candidate knows what they are worth and why they are entitled to it and will make that case directly to the hiring manager either way.
