Posts like these disturb me greatly. I remember being the younger generation that older generations loved to complain about, and now see members of my generation doing the same. Yuk.
Life skills are what are needed to navigate during one's own lifetime, not the lifetime of someone who lived 50 or a 100 or 1000 or 5000 years earlier. So what if checks and handwritten notes are largely out of fashion - dare I say approaching obsolescence? Future generations are entitled to carve out a world that they're comfortable in, just as previous generations did. For all our blowing and going about what a swell generation we were, we're leaving our descendants an ecological disaster to sort out.
BTW, I have three kids who are Millennials. All have at least bachelor's degrees, are gainfully employed and self-sufficient. Not that it matters, but all can - and do - cook and bake from scratch. Maybe they're tired of a lifetime of our generation's corporations who have been force-feeding them processed and junk foods via advertising and poor example.
Whatever it is that they can and cannot do belongs on the doorsteps of previous generations. We raised them and by our hand they learned what to value.
