Medicare Part D was a Boomer creation.
Medicare, SS, and Medicaid were not boomer creations, boomers did not make the world perfect nor totally stop the march of liberalism, but they did slow it, most of the left’s great gains were made roughly from 1935 to 1975, the left started running into a tar pit as the boomers came of age to start voting and participating in American life.
The first Presidential election in which all boomers could vote was the 1984 reelection for President Reagan. By the late 1980s the older boomers were starting to enter the lower positions of power, nothing since has been as destructive as that 1935 to 1975 period of fatal, irreversible destruction of America.
