Ryanair boss Michael O'Leary says "useless public services" like Dublin Bus, Irish Rail and RTÉ should be privatised.
He said it was inevitable that a pay deal agreed with Luas workers would lead to industrial action at Dublin Bus.
Bus drivers are planning three 48 hour strikes this month.
Michael O'Leary says striking Luas drivers should have been fired, and wants to see the Government sell the transport company.
"It's long gone beyond the point where the Irish Government should own a bus company or a train company. It should be sold, RTE should be sold.
"We should be privatising all these useless public services that depend every year on big subsidies from the tax payer because frankly, the tax payer has better things to be spending the money on."
