These terms are not interchangeable. 'Pro-business' policies often protect incumbents through regulation, leading to cronyism and cartels. 'Pro-market' policies foster open competition, which is the best defense against corporate corruption and monopolies.

The Democratic party's focus on antitrust, according to Warren, is not anti-business but fundamentally pro-market. By preventing monopolies, it fosters a competitive environment where companies are forced to continually innovate to succeed, unlike giants who grow complacent and raise prices.

Arthur Brooks argues that when free enterprise is unmoored from morality, its proponents seek to eliminate competition rather than engage in it. This leads to corner-cutting and cronyism. True capitalism, like sports, requires a shared belief in rules and the value of a worthy opponent.

The ideal role of government is not to be a player in the economy but a referee. It should be small but strong, focused on creating a fair and safe playing field, enforcing rules, and preventing the emergence of monopolies, which are a natural tendency of unchecked markets.

Counterintuitively, a genuinely free market is not a lawless one. It requires government restrictions to prevent predatory multinational corporations from creating monopolies. Without such regulations, monopolies would destroy the fair competition that is the basis of a free market.

Even markets seen as bastions of pure capitalism, like Wall Street, are heavily structured with rules like trading hours, circuit breakers, and insider trading laws. The field of "market design" shows that economies aren't natural phenomena but are intentionally structured, whether for kidneys, stocks, or raisins.

An effective government acts like a referee, creating and enforcing fair rules for the market "game." In contrast, a middleman facilitates a transaction. When government over-regulates, it's like sending too many referees onto the field who trip the players, making the game less successful.

Unchecked capitalism can lead to predatory monopolies like Standard Oil that consolidate power and stifle competition. Government intervention to break up these monopolies, while a dangerous game, is a necessary tool to preserve a competitive market.

Venture capitalist Bill Gurley explains "regulatory capture" as a phenomenon where established companies influence regulations to their own benefit. This tactic is used not for public good, but to block new competitors, raise prices, and solidify market dominance, particularly in industries like healthcare and finance.
