The company doesn't have an obligation to pay this money to their shareholders, ever. You might die (of old age) before you get your initial investment in Facebook shares back as dividends.
If that was deemed likely, the company's shares wouldn't be worth anything. Facebook and Google routinely do share buybacks these days (which is equivalent to paying dividends)
Shares, especially in big tech companies, are nowadays mostly valued as a commodity not for the dividend value. Even ignoring meme stocks like TSLA or GME, stocks like Facebook or Google are never going to pay back enough in dividends or buybacks to justify the price.
While yes liquidity drives share prices over the short term, as a general rule that's nonsense. What do you think it means for them to be "valued as a commodity"? Why do you think shares have any value at all, or have any connection with company performance? Over just the past 3 years facebook has paid out almost $30 billion to shareholders through repurchases and has plans to pay out $25 billion more. That's the majority of what its market cap was just 8 years ago, and it's still a growing company. Do you think it does that just for the fun of it?
