This doesn't mean there is no risk.
Also JL Collins' book "The Simple Path to Wealth" is well worth a read, on the same topic. If you don't want to get it, this talk covers the basics: https://youtu.be/T71ibcZAX3I

The hard challenge in the field is how to attract customers that are not quite savvy enough to figure out how to open their own brokerage account but not people so clueless as they'll go into old age with a 100% allocation to stocks. The more accessible the higher earning (ie, riskier) options are to unsophisticated the more catastrophic the backlash will be when the bad years arrive.
In a sense the regulatory system evolves to make the cheap-management options harder to find and tailored financial advice easier, because the people who aren't already in the market are going to get eaten alive making rookie allocation errors.
I know Robinhood and <insert any other brokerage> supports this, but a centralized platform dedicated to index and mutual funds that focuses on them out of the box might make sense.
If you're just interested in index funds themselves, then take a look at vanguard.
Too many people buy just one investment, not understanding they can reduce their financial risks buying several unrelated things. For example, only owning a house. And refusing to buy stocks because of risks.
But Vanguard aside there are loads of low fee ETFs from ishares, amundi lyxor, etc eg https://www.xetra.com/xetra-en/instruments/etf-exchange-trad...
