Earlier quoted context omitted.
Non-profits don't have to avoid profit. The difference is what they do with any profits; they can't distribute it as dividends to owners/shareholders.
I think the point is the same, and somewhat interesting. Do most hopspital non-profits channel their profit into growth or price discounts. In my opinion, it is fairly common for non-profits to adopt growth as a goal in of itself, and try to extract as much value as possible from customers to further it
Non-profits are not obligated to hide/spend their profits. They're allowed to accumulate fabulous wealth if they want (see, for example, Harvard's $50B endowment).
Non-profits, in theory, serve a societal/community purpose rather than existing to make a profit for their shareholders. You're not wrong that some of these lose sight of these purposes in favor of a bunch of MBAs telling them "growth! growth! growth!" (and the CEO salaries that come from such growth), but it's not because the IRS requires them to.
The problem isn't tax law; it's the "everything must always grow or it's a failure" economy we've set up.
