Unless you're the only one selling a product that people need and want to buy you're going to be undercut by your competitors that aren't paying for these things either as that is how it works in America. Quite expected when there's no worker shortage so companies have to compete for workers, but that's not the kind of competition capitalists want.
In most of Europe workers wouldn't have to worry about any of that, everyone enjoys the basic package. So your competitors wouldn't be able to undercut you on price by not providing healthcare and thus force you to do the same.
Is it the best system for startups, corporate profits and the stock market? Obviously not but people are happier.
