> what is the corporate tax rate?
21%
> It's not 100%, so you're deducting a fraction developer's salary from your income, right, you're not saving that much on your tax bill each year. you're paying tax on the income you used to pay the developer.
Which is a problem if you don’t have the money to pay the tax.
Let’s combine your and the parent’s examples: 1 principal engineer @ $300,000/year; 3 engineers @ $200,000/year = $900,000/year. $1,000,000 in sales.
year 1: Company makes $1,000,000 and pays $900,000 to engineers for a $100,000 cash profit; it deducts $180,000 from $1,000,000 for a $820,000 paper profit, and owes $172,200 in taxes. Since $172,000 > $100,000, it has a $72,000 cash loss for the year. There is not year 2.
Or maybe it raises enough capital to have a cash cushion. A similar thing happens in year 2: it makes $1,000,000 and pays $900,000 to the engineers for a $100,000 annual cash profit, deducts $360,000 from $1,000,000 for a $640,000 paper profit and owes $134,400 in taxes, still more than the cash profit. The cumulative cash losses are now $106,400.
Once again in year 3 it makes $1,000,000 and pays $900,000 to the engineers for a $100,000 annual cash profit, deducts $540,000 from $1,000,000 for a $460,000 paper profit and owes $96,600 in taxes. Hey, it doesn’t owe more than it made in taxes! On the other hand, its cumulative cash losses are now $103,000. Three years, three million in revenue, 2.7 million in expenses but it’s in the hole by $103,000, still more than its annual profit.
In year 4 it makes $1,000,000 and pays $900,000 to the engineers for a $100,000 annual cash profit, deducts $720,000 from $1,000,000 for a $280,000 paper profit and a $58,800 tax bill. It still has a cumulative $61,800 cash loss.
In year 5 it makes $1,000,000 and pays $900,000 for a $100,000 annual cash profit, deducts $900,000 from $1,000,000 for a $100,000 paper profit and a $21,000 tax bill. Good news, the company now has a cumulative cash gain! At the end of five years and $5,000,000 in sales the capital owners have made … $17,200. The engineers made $4,500,000 and the government made $483,000.
In year 6 it makes $1,000,000 and pays nothing (this is very unrealistic, because in the real world every product requires maintenance …) for a $1,000,000 cash profit, deducts $720,000 from $1,000,000 for a $280,000 paper profit and a $58,800 tax bill. People complain that it’s only paying a 5.88% tax rate, ignoring the years of amortised losses. But hey, after $6,000,000 in sales the owners finally have $958,400. They take it as a dividend and it gets taxed at the top marginal rate, so they pay an additional $354,608 in taxes.
In the real world, of course, sales may or may not cover salaries, sales may increase or decrease from year to year, markets may change and so forth.

That’s an impossible target. Any random person can say, unreasonably, that someone else is a ‘lamprey on society.’
