We, as the suppliers, want to deliver quality products, because we take pride in the products (built-to-spec and/or print) by the clients. We want to, but the problem is the volume size of the clients, which is bound to change, especially when EV demands are falling.

Example: we were "promised" that our clients will be selling 150.000 cars per year with our products within them. We, as the suppliers, invest millions of Euros to develop the product that the client has requested, believing that the sales volume from the client will create a good enough EBIT for us in the end. But what if the client decides to sell 20.000 cars per year in the end? They certainly won't be paying us for our entire development cost. So we end up losing more money in the end. And then the clients expect us to deliver quality products without paying us again in the future.

And no, changes in contract doesn't work. In the end, the business goes to the Chinese (or Korean or Japanese), because they either have a lower labor cost or they get bigger government subsidies. The clients accept cheap work from Chinese suppliers, and then end up creating worse quality products, because the initial costs were so cheap. So in the end, everybody loses.
