Foreign companies owned the telephone systems and power grids that Latin American countries needed to function. International Telephone & Telegraph and American & Foreign Power charged high rates and resisted local control until governments began nationalizing them. When Allende moved against ITT in Chile, the company offered the CIA a reported million dollars and pushed to wreck the economy, though it was an eager instigator rather than the puppet-master.
How much ITT's offered money actually did is uncertain. The record shows ITT offered funds and urged destabilization, but the CIA ran its own operations and rejected some ITT proposals.
