Tradition tells us that Christ wasn't insulated from earthly duties, such as running a carpentry business.
Was he a sole practitioner or was he St. Joseph's employee?
Were he and St. Joseph partners?
Did they hire employees?
What kind of wages were paid?
Did they charge nothing for their services?
Did they charge a below-market rate?
Did they make a profit?
Did they borrow money for expansion?
Did their business ever fail?
Were their estimates accurate?
Any cost overruns?
