In her maiden speech O'Neil placed an emphasis on the importance of a strong economy in effecting a fair society and stemming disadvantage. She stated that while she believed "government should not be building great tariff walls or controlling the big macroeconomic levers", it did in practice provide "the platform on which our businesses compete – and win – globally" and that political leaders must therefore play a role in providing "good policy and clear communication" on the topic. O'Neil cites her family's history, work at McKinsey & Company, and experiences in indigenous communities as influential in shaping her views on the economy.
