Except a 401k gets taxed on withdrawals, potentially at a higher tax rate than you were paying when you invested some or even most of it. Also, we can’t invest our whole salary into a 401k, as there’s a hard limit on contributions. Whereas a business never gets taxed on the assets they invested in to offset their profits (except maybe state/local property tax, but then they get to deduct that from federal tax…), plus they get to deduct the depreciation of said asset for years going forward.
Same with “associate” or “partner” instead of employee. Garbage nonsense. It’s insulting.
