paying a peasant to work
Peasants (serfs) were not paid. They were bound to the land they worked, and were given a fraction of the harvest they produced. The rest was property of the Lord who’s title controlled the land.
There was a (very small) artisan class where the concept of payment existed, though often it was payment-in-kind - smith the plow for my oxen and I’ll give you some food after the harvest. Money was rarely encountered for the vast majority of people.
Role of thumb is an employee costs roughly twice their base salary, as the employee still needs to cover insurance, taxes, sick time, and other benefits.
That leaves an average salary of 190K for the 50 employees. That isn’t much for tech.
