If Big Law were StarCraft, there would be three races.
Wachtell is Protoss: few units, each extremely expensive and powerful, with lockstep pay, one office, minimal leverage, and fees tied to outcomes rather than hours.
Kirkland is Zerg: overwhelming numbers, a huge non-equity tier, merit-based pay that makes stars very rich, and a recruiting machine that never stops.
Weil is Terran: the balanced, adaptable establishment, with M&A for booms, restructuring for busts, and organic growth held together by institutional prestige. In theory the races are balanced.
In practice, the Terran model is being dismantled in the middle of a boom, which tells you its hedge was aimed at the wrong threat. Countercyclical practices protect revenue against the market. They do not protect partners against being bought. Once the Zerg economy can offer a rainmaker a multiple of their draw, balance and prestige stop being a defense, and Terran firms either imitate the swarm (Latham, Paul Weiss), get picked apart one partner at a time, or start taking merger calls.
So is Protoss next? Lockstep is weakest exactly where the Zerg strike, among junior partners producing at a level they will not be paid for until a decade of seniority catches up. But Wachtell does not compete for the same resource. It sells judgment on a handful of bet-the-company matters, not capacity, and it still posts the highest profits per equity partner in the Am Law 100. A few Protoss units defecting does not mean the Protoss economy fails. It means Wachtell’s real vulnerability is succession rather than market share. If the swarm keeps hollowing out the junior-partner ranks, the question becomes who is in the room in fifteen years.
That leaves the Zerg, the apparent winner, whose risk is built into its design. A swarm has to keep feeding. The model needs a vast salaried tier kept busy, a compensation system that works only while the pie keeps growing, and a client base concentrated in PE sponsors whose deal flow depends on cheap leverage and open exits. Restructuring cushions a downturn, but it cannot replace an M&A and fund-formation machine of this scale. And partners recruited with money stay for money: a platform that wins laterals by outbidding rivals is equally exposed when someone else outbids it, or when profits flatten and the stars find their draw no longer justifies the hours. A cyclical PE slowdown, Kirkland has already shown it can survive. A structural repricing of private equity is different. If that happens, the non-equity tier turns from an engine into a fixed cost, the bought loyalty unwinds, and the race that won the boom becomes the most exposed in the bust. If the PE bubble bursts, the Zergs are toast.
