I get where you are coming from with this, and I would have agreed with you some years ago.
However, the millennial's behaviors mentioned are a consequence of the energetical state of the world.
And though some might have regrets, they knew that deep in their hearts they did the right thing, for them.
I have four kids and I love them to bits.
But if I had been born in recent years I don’t believe I would want to bring kids into this world.
Like kids, pets are now shown to take on some energetical, systemic, and even karmic stuff just like you, me, and kids from their parents.
On a higher level, we are being shown/told something that is, with or without, our understanding creating a kind of balance in the world.
Of just simply a shift in truths and norms.
A shift in frequency if you will.
