The minimum wage increases ($15 now campaigns etc) started way before Sanders and were almost entirely kickstarted on the group by orgs like Socialist Alternative Party and Working Families Party.
Pretty much nothing else Sanders wanted has come to fruition and minimum wage increases happen in many states without public pressure anyway. Hell, even George Bush raised the minimum wage.
Instead what we got was a two time primary loser, and a two time billionaire as president, exactly what he didn't want.
I attended a few Bernie campaign meetings and it was very depressing. Mostly super old Democrats pushing 50+ mulling about and doing nothing. They'd hire a college student wanting debt relief, who in turn would bring in a few more college students to do phone banking. The social atmosphere of the campaign was dismal and there was no excitement.
Immediately after Sanders would lose and election, my local Sanders campaign office became a de facto Clinton campaign office. The upper class phone bankers who came for a bit of student debt relief were then ordered to start making calls for Clinton.
Both campaigns basically funnelled people into Clinton and Harris' campaign, the latter of which was the most right-wing Democratic campaign I've seen since Gore. She punched left and down, ran ads against even the smallest competitive left-wing electoral organization, and promoted a bill that defined "affordable housing" as $400,000.
The only organizational remnant of his effort weren't intention. The DSA seems to have benefited the most, seeing a 16x increase in membership over years. Even a cursory look at the organization shows a highly dysfunctional group of former Tumblr users who have no idea why they are there or what they want. Because they aren't a party, they just bicker about who to endorse all day, and now most of their alliances in state legislative bodies and Congress or either gone or dying.
Lastly, the Socialist Parties that do run their own candidates ran into larger non-socialist parties and there's probably only like a few hundred people in actual socialist parties nowadays.
