I think part of OP's frustration is that corporations (and the wealthy, for that matter) have a lot more loopholes to be able to claim deductions compared to the average person. And people are spending money to just survive, which seems more important than making a profit. The average person doesn't have the resources to access these loopholes.
Loophole example: say you're just a common multimillionaire. You want to own multiple properties, but to just go out and buy them, you'd need to spend your income on them, which you can't deduct from your taxable income. Instead, you incorporate a private consulting company (just yourself) and instead of you buying those properties, your business buys them for you. You know, so that you can have somewhere to stay when you travel for business. Those become deductable expenses, and your company doesn't pay any tax on the income used to purchase them. You pay yourself a meager $50k per year, pay almost no tax, live luxuriously, and write condescending posts on LinkedIn. Congrats, you win capitalism.
