You keep trying to change the argument from the lack of fairness in tax policy to a discussion of how you can dodge taxes by becoming a business.
Yes by becoming a business you can dodge taxes like other businesses. That's not the argument.
OP: "rent is high" YOU: "no its not, just buy a house" OP: "that's not what I said" YOU: "You're not listening, here are tips to buy a house cheaply."
You buying a house cheap doesn't change that the OP said rent is high. Becoming a business doesn't change the tax policy allows deductions for businesses that employees don't get.
And your "garage sale tip" is bullshit of the highest order. If you've done it, you are lucky you haven't been audited. You can't deduct on a loss every year without being classified as a hobby. If you are holding a garage sale, you aren't earning a profit- that's why its not taxable. You selling a 20 year old $10 beanie baby for 25 cents is a loss and you don't have to pay taxes on that 25 cents.
