"Instead of enzymes those products rely on the brute force of high pH levels which may even be a better choice on some specific stains than enzymes in insufficient amounts."
Enzymes also come into play by length of wash cycle.
For best performance enzymes need certain minimal contact time. This is generally around twenty minutes or so. Obviously given proper conditions enzymes will go to work soon as wash cycle begins, but optimal or even good results may suffer with short cycles.
Unilever and others came up with laundry detergents that will work in "quick cycle" (about 15 minutes) such as Persil's Wonder Wash.

With short wash cycles chemicals play a more prominent role in wash day.
Commercial/industrial laundries have average wash cycle of 8-12 minutes. Hence you still find same powerful chemicals of old still about; washing soda, sodium hydroxide, sodium metasilicate, etc.... If loads are very fouled two or three wash cycles may be needed, though all would be short in time.
There has been some movement to get industrial/commercial laundries onboard with enzyme products, but again this would mean often lengthening wash times which in turn extends entire cycle and affects through put.
Chemicals can (and have done) nearly same work as enzymes on wash day. However former will often require higher temperatures and over time may lessen fabric life.
Hospital laundries for ages got blood out of textiles using nothing more than soap, sodium metasilicate, and sodium perborate. This was done using one or more wash cycles at temps at or > 140 or even 160 F. What soap and pH didn't remove was bleached out by perborate.
