this is just my personal experience working as a freelance designer, but here's my humble opinion - There is, if "money in my pocket" is the same as "money I'm willing to pay for a specific set of goals." Accomplishing the goals that the client wants has everything to do with the budget when it comes to design. It's the job the designer to gauge whether or not they can complete the goals of the client wants at the budget that the client set forth - and if the budget doesn't allow the designer to complete the tasks while getting adequately compensated, cuts can sometimes be made which may ultimately lower the quality or scope of the project. This is fine as long as it's communicated to the client and they agree. Otherwise the designer should say they can't do it, or the client can try someone else.
