How would you compete with other businesses’s that either choose to lower prices or increase investment funding due to the equity’s higher ROI? The market works because all actors are buyers and sellers, and when buying, you are seeking the lowest price, and when selling, you are seeking the highest price. If you stop doing that, someone will outcompete you by allocating resources better (absent corruption). It even applies on a household level, where if you spend extra on charity or groceries or whatever, you will have a smaller downpayment to compete for the house you want. Also, generally, employee pay is highly correlate with the employer’s profit margin (outside of healthcare due to heavy government involvement).
