The column by Jim Hoagland on Sweden {"The 'Swedish Model' Is Coming Unglued," op-ed, June 12} was a disgrace. Not only were his facts distorted. His conclusions were ill-founded and cannot be left without comments.

Mr. Hoagland quotes a Swedish professor (Anders Aslund) talking about another "command economy" in Sweden. The same professor compares our country with those "in the Soviet bloc" and claims that we are on our way to the same "economic disaster."

This is simply not true. And I do not understand how anyone who has visited Sweden -- and no less how anyone living here -- can compare us with countries like the Soviet Union or Poland or Czechoslovakia.

Just look at the facts:

We have a democratic system -- and have for many decades -- with among the highest voter turnouts in the world.

In contrast to the previous Communist regimes in the East, we have always had an open market economy -- open to trade and travel, open to exchanges of ideas and culture, open for everyone to produce and compete.

We have a level of industrial production that per capita outranks almost all other nations. Our industrial investments have increased more during the 1980s than those of most West European countries.

A number of modern Swedish companies, all of them private, compete successfully on tough world markets -- like ABB, Volvo, SKF, Ericsson and Electrolux.

When our industry is reconstructed, we impose very strict environmental and safety standards.There is a massive program for cleaning air and water and getting rid of pollutions all over our country.

We have a national insurance system that allows you to stay in bed when you are sick or have had an accident, or to be home with your children when they are young, without substantial loss of income.

We have a record-low unemployment rate, only 1.1 per cent of the work force, which in practice gives every Swede the right to a job.

This is the result of a very determined effort by the Swedish people: to create a system that allows for economic progress while assuring social justice. It has been going on for a long time. In election after election, the voters have supported this system.

The way we do things in Sweden is far from perfect. We are constantly working to reform and improve the system. But generally speaking, it has worked well for the Swedes. I honestly do not see how it could be viewed as "a warning for the East." And it is an insult to Swedish voters to claim -- as Mr. Hoagland does -- that it has "run amok."

But there is another factor here. Some are trying to discredit the social welfare systems of Sweden and other states by comparisons with the outdated systems of the Eastern European countries. They point to all the failures of the Communist systems of Eastern Europe, and they claim that social democratic parties in our nations are on the same course. Professor Aslund, as quoted by Mr. Hoagland, is part of this effort.

Professor Aslund should be reminded, as should perhaps others, that social democrats in Europe have been the first to take the fight against the Communists and their ideas. We have always favored policies of democratic reform. Our members and our parties were most violently persecuted in the Eastern bloc after World War II.

But our ideas have survived, and they have appealed to voters in free elections. In country after country in Western Europe, social democrats are now governing (in Spain, France, Austria and Sweden), or have a good chance to do so soon (in West Germany and Britain). I am convinced that our ideas and our programs will also in time appeal to the voters in Central and Eastern Europe. INGVAR CARLSSON Prime Minister of Sweden Stockholm
