There used to be mostly piddling deductions for all sorts of things that you don't have today. It's probably mostly a positive to not keep track of things like sales tax in order to minimize your income tax.

Deductions also cause people to go temporarily insane - it’s fine paying 5% unnecessarily because I get 2% back on my taxes! Ignore the 3% that is gone forever …

Sales tax deduction still exists. 2017 law temporarily lowered but didn't eliminate it.

IF you itemize. 90% don't. Also, you can only deduct sales tax OR state and local income taxes but not both.
