The Great Depression and Now

There's a recent WSJ article, Taxes, Depression, and Our Current Troubles, which has some interesting parallels between now and the 1930s.  Excerpts and my commentary:

In 1930-31, during the Hoover administration and in the midst of an economic collapse, there was a very slight increase in tax rates on personal income at both the lowest and highest brackets. The corporate tax rate was also slightly increased to 12% from 11%. But beginning in 1932 the lowest personal income tax rate was raised to 4% from less than one-half of 1% while the highest rate was raised to 63% from 25%. (That's not a misprint!) The corporate rate was raised to 13.75% from 12%. All sorts of Federal excise taxes too numerous to list were raised as well. The highest inheritance tax rate was also raised in 1932 to 45% from 20% and the gift tax was reinstituted with the highest rate set at 33.5%.

But FDR did even worse:

But the tax hikes didn't stop there. In 1934, during the Roosevelt administration, the highest estate tax rate was raised to 60% from 45% and raised again to 70% in 1935. The highest gift tax rate was raised to 45% in 1934 from 33.5% in 1933 and raised again to 52.5% in 1935. The highest corporate tax rate was raised to 15% in 1936 with a surtax on undistributed profits up to 27%. In 1936 the highest personal income tax rate was raised yet again to 79% from 63%—a stifling 216% increase in four years. Finally, in 1937 a 1% employer and a 1% employee tax was placed on all wages up to $3,000.

States added to the huge tax increases.  The economic effects had to be crushing. 

From elsewhere, I looked at the 1929 stock market crash.  The market dropped from 381 (Sept 3) to 198 (Nov 13). It then recovered to 294 (Apr 17).  Thus, what happened in 1929 proper is comparable to what we've just been through.  It was only later that Hoover got things really rolling (down to 41 by 1932).  That was after he raised taxes, including higher taxes on goods due to Smoot-Hawley.  Taxing is economic friction, exactly what you don't want during an economic downturn.

So if Hoover did so wrong, which I believe he did, why do my "progressive" friends think FDR was right to do the same thing?
