Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.
In the first American Census in 1890, 90% of all Americans lived on farms. Farm work was hard and physical and done for the most part with hand tools. Farm families had large families because children provided cheap labor. The mechanical reaper could cut the crops in the field at a far faster rate than a human being. Suddenly farms no longer needed 10 people to harvest a particular crop. One could run the reaper. The reaper was only the first of many pieces of farm machinery which would send laborers from the farms. "You gotta run down, jump round pick a bale of cotton...pick a bale a day." People do not pick cotton any more. Machines pick it. They pick a bale in a few minutes. Most of the people who lived on the farms moved to the cities. Small towns that served the farmers are closing up. Small farm houses are closing up and being moved, torn down, or burned down to save on taxes.

1. Negative feedback can increase linearity at the expense of losing gain. 2. & 3. Positive feedback can result in large increases in gain until the increases becomes so large that oscillation occurs. 4. Positive or negative feedback at one frequency can result in enhanced or decreased response to that frequency.
