The point of VC funding is not to pay salaries, really. If you squint it seems close enough, but it sets a terrible precedent that most VC's wouldn't want: looking at venture funding as how the company pays its bills. That's a natural way to read your statement - but also counterproductive & undesirable.
The point of VC funding is to take a profitable business and allow it to scale. Ideally the company could turn $1 into $1.25, before funding; that is, ideally it's making money. It should be able to pay some bills.
The VC funding is helping it to make more money, faster, and shortening the loop from sales -> payment -> expansion. It's helping it to leapfrog its competitors. That's what that money should be doing.
But what if it hasn't found product-market fit? Well, it's still not good to look at the VC's as "where our money comes from." That source is supposed to be customers, and you never want the focus to stray too far from there.
