I don't know jack-shit about 3M but even assuming it's as successful as you say it is and as good to its employees as you say it is, the fact is that 3M must be taking advantage of automation or it wouldn't be able to stay in business. Somewhere in 3M's world there are machines, computer programs and other instruments of automation that have probably eliminated thousands of jobs. No matter how lovey-dovey they and their remaining employees may be. Obviously no corporation can function without any employees and it makes sense to treat the ones you have remaining with respect and decency.
You are living in a dreamworld if you think that ANY employer, if faced with the decision of how to spend a windfall, would not consider both the advantages and disadvantages of further hires, further off-shore outsourcing, further automation. Since the growth in off-shore outsourcing and automation seems to be proceeding much more rapidly than the growth in employment, my bet is that it is extremely unlikely that any significant portion of any windfall, whatever the source, will be spent on new hires.
I was also somewhat bemused by the wonderfully tender and loving relationship between 3M Corp and its workers. I think you'll find, in real life, employees are a responsibility and a burden that many employers would not only like to reduce to the absolute minimum, but have already done so. Employees have their obvious good points, but they are also, realistically, a tremendous source of liability, of potential workplace safety issues, of grievances, legitimate or otherwise, of lawsuits, justified or not, for sexual harrassment wrongful dismissal, accidental injury, they take up expensive sqare feet of rental space, require sick leave, vacation benefits, health-care plans, workers compensation fund payments, education and training, customer complaints, family emergency leave, medical leave - - you name it, I've just scratched the surface. You think the first reaction of an employer who receives a windfall is "Whoooopeee! I just got a bundle, now I can go out and hire a whole buncha people?" Not in this world, plane, not on this planet.
Some other things that seem unlikely: (1) that any business that could use extra help would not already, without waiting for government windfalls of unknown amount and timing, have made the necessary arrangements, with their bank if necessary, to hire the needed help; (2) that the amount of the windfall will be large enough to cover the hiring of new help; and (3) that a substantial part of the windfall, if not all of it, would not be used to pay down over-extended credit margins.
