Framing in Maslow's pyramid [1]: Many of the goods/services the gov provides fulfill either level 1 physiological needs or level 2 security needs.
Social networks fulfill level 3 and 4 needs: love/belonging, and esteem.
We aren't yet at the point where we as a society decide we need to dedicate collective resources (taxes) to level 3 and 4 needs, especially while our level 2 and 1 services/goods aren't improving at the rate with which they did in the 20th century, and are in some cases deteriorating/being privatized.
