1. It's not a bill, its a resolution.
2. Oh look, another US politician that doesn't understand the concept of socialism outside of a middle school education with an American, Cold War-inspired, us/them adversarial framing of the concept.
From the resolution:
Expressing the sense of the Senate that socialism poses a significant threat to freedom, liberty, and economic prosperity.
Whereas Merriam-Webster Dictionary defines socialism as—
(1) ‘‘any of various economic and political theories advocating collective or governmental ownership and ad-ministration of the means of production and distribution of goods’’; and
(2) ‘‘a system of society or group living in which there is no private property’’; Whereas socialism and the policies advocated by self-de-scribed ‘‘democratic socialists’’ have an underlying histor-ical connection to the Marxist theory;
*Slaps forehead*
None of these definitions bear any relationship to socialism as its been applied outside of the Eastern Bloc in the last ~60 years, and none of them bear any relationship to "socialism" as its being used by the vast bulk of the US liberal left, barring the extreme end of the spectrum.
In this sense 'socialism' is a fictitious bogeyman invented to score political points.
3. Here's the second to last bill cosponsored by the senator in question:
S.2247 Cosponsored — A bill to amend titles XI and XVIII of the Social Security Act to provide greater transparency of discounts provided by drug manufacturers, to establish requirements relating to pharmacy-negotiated price concessions, and for other purposes.
I smell hypocrisy.
