“I am paid every two weeks” != “I am paid for my time”. Social security also pays out biweekly, and it has nothing to do with time

Both salary and hourly roles ultimately have expectations around both time spent and work contributed. On average, in both cases, the time spent portion is tracked more closely while the worked performed portion is functionally given more leeway.

That’s why the original comment nails it in the first two paragraphs. It may not be intended this way, but effectively people are paid for their time much moreso than their output.
