A new chapter in British gambling opened quietly this week, not in a London boardroom but in the form of an American lottery crossing the Atlantic. Powerball, long a fixture of the American imagination of sudden, life-altering fortune, has arrived in the UK, offering a £322 million jackpot that reframes what British players have been taught to expect from a four-pound ticket. Whether this marks a lasting transformation of the UK lottery landscape or simply a glittering addition to it, the question of what we are willing to dream for — and at what cost — has rarely felt more tangible.
