Yes, it is a principle of our tax system that expenses incurred in earning income by a business should be tax deductible. However, investing in property to reap a capital gain doesn't seem like the way to grow the economy, and it means people trying to purchase a home to live in have a harder time buying. Tax is not the cause of the problem, but it does contribute.
