Immigrating ten million people sounds terrifying, but spread over five years, that's only two million immigrants per year.
Based on Austria's current population base and a growth rate of two percent, the native population increases by over 1.7 million each year, actually a bit more.
In an era without any entertainment activities, people were still keen on procreating. Coupled with Vienna Government's fertility subsidies, Austria's population growth rate has always been one of the highest in the world.
The total native population hasn't decreased much, but the impact is still significant. We are now at the heart of the second industrial revolution, with the scale of emerging industries continuously expanding and the demand for labor constantly increasing.
The demand for labor is increasing, but the supply is decreasing, leading to changes in the labor market supply and demand relationship. A rise in labor costs is inevitable.
