The Republican Party gave us the Great Depression of 1929 under Herbert Hoover, caused by Republican policies under Calvin Coolidge.
President Franklin D. Roosevelt, the Democrats, and the New Deal programs saved millions of Americans in the years from 1933 to 1939, when the military buildup for a potential entrance into World War II finally led to a total recovery of the economy.
Earlier, in the 1870s, Republican President Ulysses S. Grant presided over the Panic of 1873, which lasted until 1879, also under a Republican Congress.
In the early 1890s, Republicans, under President Benjamin Harrison, undermined the economy, and as Democrat Grover Cleveland succeeded Harrison in the White House, America entered the Panic of 1893, which did not end until 1898, and entrance into the Spanish American War.
And in late 2007 until early 2009, we had the Great Recession under Republican President George W. Bush, the worst situation since Herbert Hoover and the Great Depression, and it took the entire Barack Obama Presidency to bring unemployment down from 10 percent to under 5 percent, and the stock market grew by close to 250 percent.
Obama accomplished a revival that was greater than FDR, and without going to war.
Now, the Republicans are trying to ram through a massive tax cut for corporations and the wealthy top one to two percent, which will further harm America. It is likely to lead to another Great Recession, made worse by the likelihood that the Republicans will attempt to undermine Social Security, Medicare, and Medicaid in 2018, because of lessened funding with the cut in taxes collected. This will force massive cuts in the social safety net of the New Deal of FDR and the Great Society of President Lyndon B. Johnson.
