I believe capital gains tax for single-home owners is unfair

I mean, do single-home owners buy and sell houses just to make a profit..?
Most people sell just to upgrade to a different home.
But then they impose capital gains tax on that, and even charge acquisition tax on the new home they are buying.
No matter how I look at it, I believe capital gains tax for single-home owners should be tax-exempt or the exemption limit should be raised.
Since both capital gains tax and acquisition tax are so high, people simply stop trading.
