I read the English version (which is rather short) and didn't quite understand: did the government try to buy up shares of IKEA and take it over in the interest of the state/workers?
The end goal was to take over companies and be owned by the unions.
This had disastrous consequences for Sweden, many companies left, one was IKEA. It created an hostile climate, instead of the previous decades of consensus between buiness and politics it created an antagonistic atmosphere.
The Social democrats lost their first election in 40 years.
The system was scrapped in the early nineties.
Kamprad got paranoid over the realization that politicians and bureaucrats could take over his life work and thus he moves to Switzerland and then created this non-profit to make sure it always remained in his family.
