What does max lotz see as the primary problems of mine work

Max Lotz antagonized the unjust treatment of mining corporations towards the miners of his time:

1.) Workers are pressed with long working hours.

2.) Rapid and inhuman pacing of work.

3.) Massive safety problems.

4.) Capitalism where profit was considered more important than the labor force causing the managers of that time to milk laborers more to meet the initial investment of their corporations.
