Which in itself is complete bullshyt. The idea that Zuckerberg is a billionaire because he didn’t buy expensive clothes(which is a lie too btw) is nonsense.It could be a dumbass meme, in itself, but the principle and intention behind it isn't.
Think of it like this: say you take away the exact amounts of the clothes, and you look at what they cost in relation to the net-worth of the person buying them, and it becomes clearer on what the meme is trying to state. The broke person spent well beyond their means, buying clothes that they can't really afford, instead of investing that money that's going to generate more money. Whereas the billionaire became a billionaire because he didn't invest all his money into overspending on clothes he couldn't really afford.
Your ability to be a billionaire or not a billionaire has nothing to do with your investment in clothes. There are about 2500 billionaires on this planet, out of about 7billion people.
