Pulitzer-winning creator of 1619 Project doesn't understand how investing money can create jobs

Even I, stupid as I am, remember that bit from The Simpsons: "Money can be exchanged for goods and services". A business is doing well and would like to expand, but it hasn't enough money on its own to do that. It can borrow money from the banks, but if people come along and invest their money - that is, give money to the owners in exchange for a share of the business - this also works. Now the business can afford to hire on new people, expand its premises and make more goods to sell. Selling more things means more profit. Some of that profit goes to the investors, who can then decide to keep investing that money in other businesses.

Does this mean I'm smarter than a Pulitzer Prize winner?
