The Australian government is proposing to increase maternity and paternity benefits, ostensibly to encourage people to have more children. What it has not considered is how the demography will change. Even without further incentives, one extremist leader has already made a call to "outbreed" the local population. What a sure way to increase one's presence in the country, courtesy of the host government!
How long would it take to "outbreed" the locals? Let's say the birth rate of the local population is 2.5 children per couple. Each of the theoretical 2.5 children have another 2.5 children, and the 2.5 children have 2.5 more. In three generations, the population would be 2.5 x 2.5 x 2.5 = 15.6.
Now, lets say a certain ethnic group has a birth rate of 6 children. In three generations, the population would be 6 x 6 x 6 = 216. That is more than 10X faster than the rest of the country. In 4 generations, it would be 33X; in 5 it would be 80X....
Let's hope the politicians know what they are doing. Australia's enemies do not need an army to take over the country. The host government is happy to raise one for them.
