I don't think your explanation is quite right. The proper distinction to make is between "Garret Jones Workers" (named after the economist who has studied them) and "Productive Workers".
The "Productive workers" are those who generate profitable production with their time - a factory worker producing widgets, a doctor treating patients, etc. 1 hour = 1 surgery = $500 (or whatever). These workers are best viewed as a cost center - if hourly revenue - hourly cost > 0, they are worth hiring, otherwise they are not. They can be low or high skilled - doctors are a great example of a highly skilled productive worker. Software developers working at an agency would be another.
The "Garret Jones Workers" are those who generate organizational capital. As a result of their work, the revenue stream of their company will increase. Hiring them is an investment - you need to look at (NPV(future revenue generated by the organizational capital they produce) - NPV(cost)) to determine if they are profitable. Examples of this include software developers building a product or a doctor improving business practices at his hospital.
