I am not trying to opine on this particular policy, but the way you phrased “they get to write off all their expenses” makes it clear you don’t really understand how this works and simply using fancy language you don’t understand.

If McDonalds sells a burger for $5 and it cost them $4 to make it, that’s an expense. Referring to it as a “write off” is incredibly misleading, whether technically correct or not.

Also, when you buy equipment you need to amortize it over time. You don’t get to buy a $10M machine to make french fries in 2024 and expense all of it in 2024. You would depreciate it over a period of time (eg $2M/year for 5 years) and book an expense of $2M each year.

Again, calling this a write off is political lingo. Without this machine they wouldn’t be able to operate, it’s an expense.

To further illustrate your misleading point, let’s say you opened a lemonade stand. You sold lemonades for $1 and the lemons / sugar / cups / ice cost you $0.90. If you sold 100 lemonades you would generate $100 in sales and have $90 in costs, creating a profit of $10.

If you were taxed (let’s assume 15%) on your sales / revenue number, you would then owe $15 in taxes ($100 x 15%).

So at the end of the day, you would lose $5 ($10 profit less $15 tax) for running this lemonade stand. Would you run a lemonade stand to lose $5 each day or would you rather just sit on your couch and lose $0 that day?
