Your own link from earlier has this right in the header’s bullet points in reference to the bill that was actually signed into law not an analysis of a proposal from a year and a half prior:
The more than $430 billion package is expected to reduce the deficit by more than $300 billion over a decade.
The wealthy haven’t had their taxes increased so I don’t know where this $4T is supposed to come from unless IRS audits are going to find $4T worth of unpaid revenue.
