Dividend stocks and dividend etf are the most stupid investments

Just like the title says in a subtle manner: investing in stocks or etf with high dividend yield is the most stupid, idiotic investment decision one can take. It makes absolutely no sense: 1. On dividend date, the stock will decrease by the % yield, meaning you just convert x% of your portfolio into cash 2. The dividend is taxed, meaning you take some profits that are directly taxed, and if that is much you likely increase your tax rate and pay more on your other income stream 3. Selling x% of a dividendless stock becomes the same as receiving a dividend. If you are neg on your position, then no tax. If you are positive and live in a country without tax on capital gain, then that's even better. At least you are not giving the government some of you already taxed income. There is mathematically no advantage at all. Now you know what not do.
