Not necessarily. Imagine if you were super busy with lots of good work, and someone came to you with another job. You are already busy, but could maybe take one more job if it were worth it financially. So, you tell him that you could accept the job but only at a higher rate.
See, it can go both ways? Setting rates is a bit like chess and a bit like poker. You have to consider the market conditions as your major parameters, but then much of it also depends on how much you 'think' you can get, and how much you really want the job.
In a single day I might get 3 inquires and quote different rates for each.
If someone calls me and asks me to do some consulting for a client who I am dying to make contact with, sounds like a fun job, and is very attractive I might quote them $100.
If an hour later someone calls me and offers me a consulting gig for a sector and I am not interested in, requiring travel somewhere I don't feel like going, and working with people that I am not excited about, that might get quoted at $300.
So, be sure to adjust your rates based on both the market and your personal situation at the time!
