If you look at the theory of evolution, it is about optimization, under various environmental conditions and circumstances, helping to drive evolution; natural selection. Nature, left to itself, is usually very healthy and integrated, and not sick and disorganized. The former tells me efficiency, while the latter would require inefficiency, which is not natural.
If we use the correlation of evolution and morality, the best moral systems, like nature, should also be the most efficient, in terms of costs, just as natural is based no the lowest natural cost. Cost and efficiency would be an objective way to compare moral systems, since nature seems to make the most of each situation, both in singular and as a group.
The huge national debt in the USA, therefore, cannot be due to the best moral system leading. This would need to be connected to one of the worse moral systems in Government, leading. Nature and evolution, stays tight in terms of resources, and does not need to borrow from the future; eat the seed potato. This would be unnatural.
Religion is not allowed to control government morality; legal separation of Church and State. One has to conclude secular morality in the USA and the USA government is an inferior type of morality, based on its high level of inefficiency.
Picture if nature decided to evolve, based on huge deficits in resources, like the US Government immoral system. The leaders of the herd, lead the herd to wipe out their large fields of grass, until next year the fields are gone. We now need to invade and borrow fields from neighboring herds of other animals. This would be based on short term thinking, which is not how nature works. Short term thinking morality, leads to extinctions; low tier moral system. It may need to be retired until it can get more efficient with resources.
Before the 1960's, culture could do much more without government, all with little deficit spending. The basic family unit could handle many of todays social cost, that the current immoral system uses to drive the deficits. It is like nature over feeding and then dying back toward extinction; immoral virus. We may need kill the immoral virus, instead of continue to feed it. We may also need to become objective and base policy on the natural ways, instead of the wasteful unnatural ways of immorality.
