It makes finding a new job easier, but I think there's some leeway depending on circumstances.
For example, if you had been working in the same field in meaningful roles and then left or were laid off for x, y, or z reason (e.g. relocated due to family, medical issues, took extended time off for a sabbatical) - Then I think this candidate has a way better shot than someone who is already employed, but their work history is irrelevant or unqualified.
As long as there's a good reason you left your last job, you have evidence of being a reliable and strong performer, and it hasn't been too long, it probably won't affect your chances too much.
