Mankind may be close to reaching the end of that span. It won’t happen in our lifetimes, but we have reached a point where what we do and how we live can surely play an important part in determining how we will leave the Earth.. Those of us who have appreciated what we have had must surely feel a responsibility to whoever and whatever follow.
Time was when a man with an idea and an access to money founded a company, hired employees (be they one or a million) to make a product which people would be willing to pay for, and put that product on the market. For many years, this process worked very well in this country, provided a satisfactory living for most people, and built a ladder which those with even more ambition could climb.
Now, however, Humans have increased their numbers, consumed-- and wasted-- a very large part of the resources the Earth has to offer. While the resources are fast disappearing, the Population is fast growing, spreading, and consuming. It is becoming less and less possible for the President and the Government to support a population that is constantly draining the resources at hand.
The President finds himself being blamed for spending too much money-- money for projects like health (which we all need), highways (to employ people and facilitate commerce), and schools (to educate our children). The latter is probably the most urgent need we face, because the ability to think and reason is what makes Humans excel.
And by the way, while talking about employment, remember that government employees are human beings too.
If Man is to continue life upon this Earth, he must be able to recognize his mistakes and crimes, regret and correct them, and realize that he, Man, is only one of many millions of organisms which have made this Earth possible.
