I've worked big business management. All big business cycles through upsizing and downsizing. All are concerned with per capita sales.
I've also worked at Wal-Mart (twice). It's a good company to work for. You can buy their stock. You have opportunity to work your way up to corporate positions. Sadly, most of the floor managers are idiots and jerks.
Government and military jobs are no different. I've worked both. It's the nature of the beast.
Supply and demand . . . cut cost . . . cross-train times two times three times four . . . automize . . .
More money is poured into new technologies to "streamline" the business, but quality and work efficiency always declines . . . thus consumer satisfaction declines . . . blah blah blah
i'm sorry i'm rambling . . .
