Society cannot make you attractive to people. That's all down on you.

Any law or regulation or forced relationship/marriage/intimacy is highly immoral.

If people were forced to be with people they don't find attractive, they'd have the most unfulfilling relationship ever and it would show.

Any artificially forced cultural adjustment to attraction standards, if possible, will much more than likely only just about push unattractive people over the threshold meaning brittle resentful relationships.

And added to this, the competition from many other people would grow exponentially as there would be many more people now considered dateable.

The only answer to making somebody willfully attracted to you is to become that.

It may be unfair, but there is no answer to well if I can't do that should I just accept loneliness? It's sink or swim, sad for many but true. You cannot cure it as a society.
