As a Hartz 4 recipient, why am I not allowed to take out a loan for the PS5?
If you have collateral, you can always take out a loan. Nobody lends you money if they can work out that they won't get it back.
You can.
You just don't get one.
Because with ALG2 you are far below the garnishment allowance!
That means: you don't pay and the lender wants to enforce… Does he only have costs by the attempt, because you are below the limit with what you get from the state as subsistence level.
THEREFORE, no reputable institute will give you credit.
You can do that! You just have to find someone who will give you a loan for it, that should be difficult.
If you are of legal age, you can do so without a problem, provided you find a lender.
Actually, I don't like sayings like that, but maybe you should look for a job instead of paddling around with a game console. Then you can buy a PS5 with the money you've earned.
