The new anti-inflation program President Carter is planning to unveil next week already is being regarded as a toothless tiger by both liberals and conservatives.

Although Carter has not formally approved the bulk of the new package, what has emerged so far is being criticized as inadequate.

Walter W. Heller, presidential economic adviser during the Kennedy administration, termed the new Carter measures "a step in the right direction," but said they don't go far enough."

And Alan Greenspan, former top economic adviser to President Ford, said if the total Carter program is no stronger than what has been reported, "it would be almost better to do nothing."

The new set of proposals are said to include these elements:

Establishment of broad, generally worded criteria for the kind of wage price increases the government would view as acceptable - but without specific numerical guidelines, and with out any enforcement provisions.

Efforts to seek industry "cooperation" from business and labor - possibly through private panels such as the Labor-Management Committee now run by former Secretary of Labor John T. Dunlop.

Long lists of suggestions to business and labor for various steps that specific industries can take to help slow inflation in their sectors of the economy. The industries, however, would not be obligated to follow the government's ideas.

New efforts by the administration to change existing government policies and procedures that tend to spur inflation - such as ICC regulations on trucking. The administration also may propose a special White House inflation-review committee to ride herd on government actions - possibly under the direction of cabinet officers.

More careful monitoring of wage price developments by the Council on Wage and Price Stability.

A gretare White House commitment to anti-inflation efforts, with more direct involvement by the President - possibly including some "jawboning" or the use of moral susion to prod business and labor into limitimg their wage-price demands.

The proposals also is expected to allude to Carter's efforts to hold government spending to $500.4 billion in fiscal 1979 - a move the White House plans to portray as an anti-inflation step - and to the President's proposal, unveiled in December, to end the telephone ecise tax.

Critics outside the administration already are likening the plan to the President's ill-fated anti-inflation proposal of last April, which was almost universlaly dismissed at cosmetic.

However, administration officials continue to insist, both publicly and privately, that the plan will be effective.

W. Michael Blumenthal, the Secretary of the Treasury, told reporters the program would be built around "collaboration and cooperation," but won't involve controls or arm twisting.

Officials say the plan is aimed at slowing the inflation rate gradually from the 6 per cent pace now regarded as the "underlyging" inflation rate.

The view that the Carter plan would be a weak one was bolstered by the silence of labor officials yesterday. The AFL-CIO, regarded as the key spokesman for organized labor, usually has been quick to criticize even mildly-tough wage-price proposals, on grounds that they are aimed primarily at slowing wages.

The fact that high wage increase have become "built in" to the inflation rate is regarded by economists as a key reason that inflation has not slowed in recent months.

Sources said George Meany, president of the AFL-CIO, disclosed some elements of the plan to key union leaders yesterday, but asked them to keep the program confidential.
