SSI was created by the so called “Greatest Generation” in 1972, when only the very oldest of Boomers could vote. It funds those 65 and older, so Boomers have only been collecting since 2011.
EBT is simply an electronic delivery system for programs already in place, which were implemented again by the WWII Generation.
The expansion of SNAP was indeed largely passed by Boomer politicians. On the other hand, the entire SNAP program represents just $74 billion of the total $3.8 trillion of Federal spending in fiscal year 2015. Since 76% of SNAP benefits go towards households with children, and as you pointed out the big expansion came in 2009, Millennials and Gen-Xers have been the big beneficiaries of the largess.
WIC also began in 1972, so the argument that Boomers created it falls flat. In fact the big expansion of Federal debt, as another poster pointed out, has come under Obama. Once more I must remind you that Obama was elected by Millennials, not by Boomers.
I would say, yes please, do further research. You might just learn something.
Social Security became law in 1935. WAY before any Boomers were even born, before some of their parents were born.
