Europe has its problems. There is a flood of illegal immigrants from the Middle East and Africa. The pressure will continue.
The southeastern border of the European Union is generally marked by Greece, Bulgaria, and Romania. Hungary is one nation removed from that border except for a rather short border with Ukraine and another with Serbia. Hungary has announced it will build a fence along its border with Serbia to block illegal entry of migrants. There are already fences on the Franco-Italian border manned now by legions of French police. Greece has tightened its Turkish border and Bulgaria built a fence on its Turkish border. All of this to prevent or slow illegal immigration from the Middle East and Africa.
The countries of the European Union are already heavily burdened by illegal immigrants from Africa and the Middle East. More come daily. They come from war torn areas and because of social, environmental, or economic conditions to seek a better life for themselves and their families…. and from areas with very high birth rates. If the tsunami of people is allowed to continue unabated, Europe will rapidly decline socially and economically. New homes for all would be wonderful, but that is not realistic.
In the United States, we are fortunate to have the natural barrier of thousands of miles of ocean to the east and to the west that do not prevent but do slow the flow of illegal immigrants from the Eastern Hemisphere. Still many get through. Our primary problem is the border with Mexico where thousands continue to enter the United States illegally daily. Most illegal aliens that cross our southern border are from Central and South America, but others have made their way from the Eastern Hemisphere to Mexico to gain entry to the United States.
Nobody wants to talk about population numbers. The United States must adopt policies that stabilize human numbers within this country. Absent immigration, the United States and virtually all developed countries, including those in the European Union, would have stable populations. Not so the countries with continuing high birth rates. They have reached max capacity economically, socially, and with available natural resources…. yet continue to grow population numbers. There is no place to go but out. As said, the pressure on developed countries will continue and grow. It remains to be seen whether they will say NO MORE or participate in the race to the bottom.
