Laborers worth it?

[NotReally]

Prospector journals for example... go at quite good price. Each mining run I am able to fill couple and earn quite a extra profit by selling them. How profitable are laborers themself? How much titanium ore does expert prospector bring you home per journal? In average?

They do not return a huge amount. At T4 its 35ish? I assume it goes up per tier but if you have 3 its not to bad. Remember the happier they are the more chance they have to return .1 .2 and .3. If you can get .3 out of them its definitely a win.
