The correct answer is: "They thought the excessive number of regulations hurt businesses".
Conservatives supported laissez-faire economic policies.
Laissez-faire economic policies claim for no goverment intervention in the economy.

When goverments intervene to correct a market failure, they distort the natural adjustment mechanisms of the markets, reaching a worse scenario than if the market has corrected itself alone.
