You can run high-volume business and mid-level infrastructure (messaging) systems day-in day-out in Java, and struggle to see more than 0.1% CPU needed for garbage collection. The light-bulb idea here is about reliability, security and productivity. Managing memory manually a la C/ C++ is a proven disaster in all three respects. Maybe ten or fifteen years ago GC was costly, but these days it's highly efficient and not incomparable with programmatic allocation.
