fall by the wayside idiom
中途退出;半途而废
If someone falls by the wayside, they fail to finish an activity, and if something falls by the wayside, people stop doing it, making it, or using it.
So why does one company survive a recession while its competitors fall by the wayside? 那么为什么一家公司度过了经济衰退期，而其他竞争对手都中途倒闭了呢？
