I have a friend who recently passed away who made car trailers that lost money on every one he built. He went bankrupt and lost EVERYTHING he had including his marriage.
It depends how the money is spent. If you’re putting money in an investment with hopes of generating a positive return into the future, then its worth doing. If you’re putting money into money pit with no hopes of generating a positive return, then its a waste of money. Tesla is capital intensive. All money invested will generative huge returns in the future. People shouldn’t think short term, but long term. Investment is not gambling, it takes time
