It has always been that way. In 'How to win friends, and influence people' Dale Carnegie brings forward this wonderful concept of letting people win arguments, suffering fools gladly, and almost always agreeing with people. Unless something very big is at stake.
Giving advice, being critical and helping people through feedback is almost always a bad idea. For starters you must let people fail. This has benefits, it helps them learn from experience and is a character building experience. If the person refuses to learn from experience, well then whatever feed back would be useless anyway.
Just see how many people require walking around them on egg shells. You have to handle their feelings with kid gloves, or have your career destroyed.
Even in general things, good advice is available in mainstream media and advice for ages. People still have bad finances, and lifestyle diseases. Advice, feedback mostly don't work.
