>[edit] Another that I should probably mention is the treatment of asset depreciation; in the 1960's and 70's the government was incredibly generous with regards to asset depreciation.

That is pretty much how it is today as well. 100% bonus depreciation, Sec. 179, and the safe harbor for writing off pretty much any item under $2,500 as an expense, are all in place currently, and the favorable treatment of subsequent gain from sale is still there too.

I think 62-21's creation of broad industry classifications expanded rates of depreciation for a wide variety of assets, though; I'm pretty sure that was re-structured in the 80's, not sure if it was part of the 1986 Tax regulations but likely around that time.
