This is very misleading.

Only the top few US law firms (e.g. Wachtell, Cravath) are on lockstep at that scale. Most other US firms pay according to an eat-what-you-kill basis where compensation is tied directly to origination. New partners at such firms are unlikely to get anywhere close to USD2 m in their first year, more like 500k-1m.

Nevertheless, a US partner will often outearn an SG partner at the same level of seniority.
