the bank just to save your money and for security you have to pay a fee to the bank, so how can it be rich if saving money in the bank. invest better if you want to be rich because your money will increase, will not decrease as it keeps your money in investment. unlike in the bank that charges you.
I can't agree with that, because it's not always secure to hold money in the bank, if talk about large amounts, because of many situations in past when banks had troubles and people who were holding there large amounts of money, lost them. Also about deposits, in my country interest per year around ~15%, but because of the unstable price of the national currency, after year, your profit will be eaten by inflation.
