Why are we using load balancer to balance the load of load balancers while horizontal scaling?

We added more load balancers to handle more traffic, now we are saying add 1 more load balancer, which will balance the load among all the load balancers (It will act as a top level load balancer). Now that load balancer which will route the traffic to the other load balancer, will it not face the same kind of traffic issues and failure issues?

I think, while we are increasing load balancers, to manage spike in traffic, we should also add backend servers for these new load balancers, so traffic can be shared.

Also, there is nowhere mentioned that we are adding a top level LB.

When horizontally scaling load balancers (adding more load balancer instances to handle increased traffic), it doesn't mean implementing a top-level load balancer to distribute traffic among these load balancer instances.

Instead, DNS load balancing can be used to dire...
