ELI5: Why is marriage important or is it still relevant? Why does the state give lots of "perks" to married people?

The state has an interest in raising the next generation of well adjusted children, and believes that occurs best in the context of marriage.

Also, many homes still have the breadwinner/homemaker structure, with one spouse focused on work, and the other focused on caring for the family.  The homemaker takes on a serious financial risk, as they are sacrificing their ability to make a living to  support someone who could leave at any time.  Marriage enforces this commitment, and provides for the homemaker should the marriage dissolve.
