Bonn Favors E. Germans’ Benefit Cuts : Europe: The continuing influx of immigrants from the east is causing resentment. A change in treatment of new arrivals is expected.

The major West German political parties are lining up in favor of a crackdown on some of the benefits automatically extended to immigrants from East Germany.

The policy change is expected to be made after Sunday’s national election in East Germany, according to political sources here.

The continuing influx of East Germans, at a rate of more than 2,000 a day, has been an increasing source of friction in West Germany’s affluent society as refugees from the East take up scarce living space in cities. Now a rising tide of complaint by West Germans that East Germans are straining their social services has forced the government to agree privately to cancel some benefits, such as preferential emergency housing, that are given the newcomers.

Government sources said Tuesday that measures curbing benefits might be announced as early as this week. They said the issue is on the agenda of next week’s Bonn Cabinet meeting.

Over the weekend, Oskar Lafontaine, the premier of Saarland state and the opposition Social Democrats’ likely candidate for the chancellery in West Germany’s next national election, announced that his party would end most of the benefits given East Germans.

Under his plan, incoming East Germans would receive pensions if they are of retirement age, but the pensions would not be as high as those for West Germans who spent their adult lives working for their own pensions.

Further, he and other politicians have called for a wide range of measures that would keep East Germans from coming to the West.

Lafontaine said the money used to provide emergency services to East Germans could be better spent building up East German roads and cities to help keep would-be refugees at home.

At the same time, Wolfgang Mishnick, the leader of the Free Democrats, the junior partner in the West German governing coalition, declared that emergency housing for the “resettlers” should be stopped after Sunday’s election.

Most West German cities can absorb few additional immigrants, who are now housed in gymnasiums, converted freight containers, air raid shelters, church grounds and even on ships in ports such as Bremen and Hamburg.

Sixty-four cities and towns in the most populous state of North Rhine-Westphalia, including prosperous Duesseldorf, have imposed a two-month ban on newcomers from the East; others refuse to accept them altogether on the grounds that they are already overcrowded.

Of the nearly 150,000 East Germans who have arrived in West Germany this year, only an estimated 10,000 had homes to head for.

When the exodus from East Germany began last summer, many West German cities and citizens welcomed the newcomers, seeing them as brave young people fleeing Communist oppression.

But with the razing of the Berlin Wall and the liberalization of the East German regime, most West Germans now view the newcomers as purely economic refugees looking for a better life. And the increasingly bitter feeling is that they are seeking that better life at the expense of West Germans who have worked hard for what they enjoy.
