I'm surprised and dismayed at changes to 401Ks and similar retirement plans. I would have expected them to be attached to that 3rd rail of politics, Social Security.  But what Caesar gives, Caesar can take. 

I like the increase in the personal exemption. I'd like to see that be the ONLY exemption allowed, and increased to (poverty level for family of four)/4. Eliminate the different tables for single, married, etc. too.  Just add a group of people's income, take personal exemptions for each member, and apply the tax table. 

Pres. Trump is very wrong when he says, “It will be the biggest tax event in the history of our country,”. The 16th Amendment still holds that title, IMHO.
