Why is there so much bullshit in life?

When did life become so complicated and difficult? What ever happened to the simple, work 9 to 5, bring home a paycheck, kiss the s/o on the cheek and relax for a few before dinner. Work for a company that takes responsibily for their workers, provides a nice retirement, and good benefits. What’s the upside to today’s workplace? And why do people treat those around them like crap. Can we at least be a little nicer to the people we come in contact with?
