1) the ”owner” is long dead.

2) the foundation is set up in such a way to perpetuate itself and its goal (to better mankind), forever. Not to generate wealth for Ingvar Kamprads offspring. He hardly left them penniless. His family does not control his foundations. They have a minority vote.

3) if the world’s billionaires set up their organisations in similar ways, the world would be a much better place.

Ingvar Kamprad is known to have lived a simple lifestyle, despite being one of the wealthiest men while he was still alive. While travelling he stayed at cheap hotels and drove an old Volvo. Does this strike you as a man motivated by greed?

From your article: ”That control is so tight that not even Mr Kamprad's heirs can loosen it after his death. The foundation's objects require it to “obtain and manage” shares in the Ingka Holding group. Other clauses of its articles require the foundation to manage its shareholding in a way to ensure “the continuity and growth” of the IKEA group. The shares can be sold only to another foundation with the same objects and executive committee, and the foundation can be dissolved only through insolvency.”
