Basically the same in Sweden. Many fines are defines in days wages rather than in fixed amounts. So the judge will simply fine someone 30 days wages and not worry about what that amounts to for that particular person
Well obviously, but that is true of all fines. And you cannot argue that a system where the poor person pays $1000 and the rich person $4000 is harder on the the poor person than a system where everybody pays $2500.
