All of these economies are running on fumes: there just isn't enough demand across the board for a stable continent-wide situation.

Europe is a rich, stable continent with an ageing population, surrounded by poor, unstable countries with lots of young people.
The Kosciuszko Uplift tectonism occurred at rates greater than typical of passive margins, and belies Australia's reputation as a tectonically stable continent.
Progress here could be the difference between a prosperous Africa and a slowly declining, less stable continent, with global repercussions.
It is well known that bedrocks form erosional plains in Australia after very long-term erosion on the stable continent.
However, earthquakes events such as 2001 M7.7 (Bhuj), 1993 M6.3 (Killari), 1997 M5.7 (Jabalpur), and 1967 M6.5 (Koyna), stressed the need for the revisiting of the stable continent belief as manifested by intra-plate earthquakes.
Although no one knows when the first outer crust of the planet formed, some scientists believe that the existence of a few grains of zircon dated to about 4.4 billion years ago confirm the presence of stable continents, liquid water, and surface temperatures that were probably less than 100 °C (212 °F).
Non-active regions, located far from volcanoes or faults, indicate the smallest ratios, although the ratios are larger than those estimated on stable continents.
