Persistence | Previous waves of immigrants eventually subsided, the proportions coming from individual countries fluctuated greatly, and, after 1924, immigration was reduced to a trickle. In contrast, the current wave shows no sign of ebbing and the conditions creating the large Mexican component of that wave are likely to endure, absent a major war or recession. In the long term, Mexican immigration could decline when the economic well-being of Mexico approximates that of the United States. As of 2002, however, . gross domestic product per capita was about four times that of Mexico (in purchasing power parity terms). If that difference were cut in half, the economic incentives for migration might also drop substantially. To reach that ratio in any meaningful future, however, would require extremely rapid economic growth in Mexico, at a rate greatly exceeding that of the United States. Yet, even such dramatic economic development would not necessarily reduce the impulse to emigrate. During the 19th century, when Europe was rapidly industrializing and per capita incomes were rising, 50 million Europeans emigrated to the Americas, Asia, and Africa.
Finally, some critics have questioned whether Leopold's land ethic might require unacceptable interferences with nature in order to protect current, but transient, ecological balances.  If the fundamental environmental imperative is to preserve the integrity and stability of natural ecosystems, wouldn't this require frequent and costly human interventions to prevent naturally occurring changes to natural environments? In nature, the "stability and integrity" of ecosystems are disrupted or destroyed all the time by drought, fire, storms, pests, newly invasive predators, etc. Must humans act to prevent such ecological changes, and if so, at what cost? Why should we place such high value on current ecological balances? Why think it is our role to be nature's steward or policeman? According to these critics, Leopold's stress on preserving existing ecological balances is overly human-centered and fails to treat nature with the respect it deserves.
3. We look at ourselves a special nation and our foreign policy of intervention and getting involved shows this. This is a direct result of the idea of being a "city upon a hill."

But are these transfer payments and ‘entitlements’ affordable, in either economic or moral terms? By continuing and enlarging them, do we subsidise sloth, or do we enrich a debate on the rudiments of the good life?
