Uncontrolled private enterprise, such as the General Motors Corporation, threatens to destroy all economic freedom and with that political freedom, Senator Joseph C., O'Mahoney (D-Wy.) declared last night.

"If the present concentration of power in a few private hands is allowed to exist, the system will eventually become a dictatorship," he told a New Conservative Club meeting. "General Motors is an economic state which controls or deeply affects every state's economy," he said.

For the past five weeks O'Mahoney, Chairman of the Anti-Trust and Monopoly Subcommittee of the Senate Judiciary Committee, has been conducting hearings on violations of monopoly positions by big business and General Motors in particular.

Citing figures gathered in the course of the hearings, he showed how giant corporations, with over $100 million in assets, have increased their net capital by 76 percent since 1952, while the assets of $1 million corporations have fallen in the corresponding period.
