I don't really know why people were ever allowed to deduct state tax in the first place. Seems like a way to subsidize states with high tax rates. For me and the amount of money me and my wife make it looks like our taxes would go down just a little. If the lower corporate tax rate creates jobs and grows the economy in the 4% range over the next 8-10 years I am all for it. And if your mortgage is over 500k you probobly gonna be ok. Very small percentage of people live in a house worth over 1/2 million dollars.
