@geekwithsoul.MS's 257.31B market cap is based on a hundreds of software products and devices most of which are profitable. Google's on the other hand is based primarily on 1 product, search engine, on which it makes boat loads of money. Its a good product, arguably the best but there is a catch.I can tell you first had how expensive it is to advertize on Google, it can easily cost upto 10$ per click for ordinary keywords and given that Google is the gateway to the internet for over 90% of users not advertizing on Google is not an option. You might think you are not paying for it so what's the big deal , aah hha but you are. Advertisers have to jack up the prices accordingly to pay for these super expensive clicks, so in essence you pay for the billions of dollars Google racks in.So in short there is a Google tax on everything you buy, it just doesn't show up printed on your receipt.
