> A lot of growing companies have US taxes that are quite low because they lose money for a long time while they're investing in growth. When they finally become profitable, they're allowed to roll forward those losses (within limits) to offset their profits.
Human beings cannot do the equivalent. Spend the entirety of your 20s making very little money because you are investing in growth and then make $800k as an orthopedic surgeon at age 30, and you’ll pay the top marginal rate. You don’t get to go back and use all the unused 24% bracket income from prior years. You also can’t deduct the interest on the loans you took to finance that growth.
