You should care because for long term investing, an actively managed fund is very likely to underperform the market. The vast majority of hedge fund managers aren't doing anything that you couldn't do yourself, i.e. pick a few stocks out of the S&P 500 and hope that they outperform the market.

Look into index based ETFs. They simply track an index so your performance is equal to the market's, so no handpicking stocks or gambling. They are traded like stocks, so you can probably buy them with your broker. The best part about them is that they have almost no fees - the most popular ETFs cost 0.10-0.20% per year.
If you're American and believe that the American stock market will continue to outperform the rest of the world, then an ETF like SPY (tracks the S&P 500) would be a good bet. If you'd like something more diversified, have a look at funds tracking indices like the MSCI World or FTSE All-World.
