Most Americans don’t realize how different their campaign finance system is from the rest of the developed world. While political spending in the United States has become a free-for-all following a landmark Supreme Court decision, many of America’s closest democratic allies have taken a sharply different approach — one that treats unlimited private money in politics as a threat to democracy itself.
France, Canada, Belgium, Portugal, and South Korea have enacted strict laws that either cap individual political donations or ban major private contributions entirely. France limits individual donations to political parties to €7,500 per year — and corporations are prohibited from donating at all. Canada goes even further, banning corporate and union donations outright, with a hard individual cap of just $1,675 Canadian per year. South Korea also prohibits corporations from making political donations. The common thread across all of these countries: money in politics is treated as a policy problem to be regulated, not a constitutional right to be protected.
These laws are not theoretical. They are actively enforced. In France, political parties that accept illegal donations face criminal penalties, and independent commissions monitor compliance year-round. Canada’s Elections Act disqualifies candidates and parties that violate financing rules. These systems are designed around the principle that political representation should be determined by votes, not by the size of a donor’s checkbook.
The argument behind these restrictions is straightforward: unlimited money buys disproportionate political access. Supporters of donation caps argue that when billionaires can write unlimited checks to Super PACs supporting candidates who advance their financial interests, ordinary voters effectively lose their voice. The election becomes less about who has the best ideas and more about who has the most powerful backers. Reformers say these restrictions make elections more representative of what the average voter actually wants — not what wealthy donors are willing to pay for.
America went the other direction. In 2010, the Supreme Court’s Citizens United v. FEC ruling cleared the way for corporations, unions, and outside groups to spend unlimited amounts on elections through Super PACs. The majority opinion held that political spending is a form of protected free speech under the First Amendment — and that the government cannot restrict it simply because the speaker is a corporation or a billionaire. The dissenters warned that this would open the floodgates to corrupting influence. Both sides turned out to be right about what would happen. The only disagreement is whether what happened is a problem.
The numbers are staggering. The 2024 U.S. presidential election became the most expensive in American history, with total spending exceeding $15 billion. Individual donation limits to candidates technically still exist under federal law, but the overall system allows for a scale of private political spending that most established democracies expressly prohibit. A single donor can route hundreds of millions of dollars through outside groups, dark money nonprofits, and Super PACs — all while technically complying with the letter of the law.
Critics of campaign finance reform argue that the alternatives come with serious trade-offs. Limiting political spending, they say, means limiting political speech — and the government deciding who gets to participate in political debate is its own form of corruption. They point out that some of the countries with strict donation caps have their own forms of political favoritism, and that restricting private money doesn’t automatically make a political system more democratic.
The debate over whether America’s campaign finance system is corrupting democracy or protecting free speech has never been more pointed than it is today. Seven countries have already made their choice. Now the question is being put directly to the American people: Should the United States make it illegal for billionaires to fund political campaigns?
