I'm not going to pretend Harris is not the only sane yet realistic option atm, but those "policies", at least what's shown in that screenshot here…
Those aren't policies, those are empty feel-good slogans. They are ambitions at best, and extremely vague ones at that. You could come up with just about any actual policy from just about any political camp and make a passable argument for how it fits in there.
They're from her campaign website, and they expand to give more detail.
That said, while the meme calls them policies, the website only lists these as issues. It's a general outline of her positions, not drafts of proposed legislation or anything like that.
