It's easy to believe that "the end of this age of grace is near." Indeed, the Bible refers to this age in which we're living as "the last days." The times described in II Timothy 3:1-5 certainly sound like Planet Earth circa the 1990's - "This know, also, that in the last days perilous times shall come, for men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, traitors, heady, highminded, lovers of pleasures more than lovers of God, having a form of godliness, but denying the power of it; from such turn away."
All the behaviours you mentioned has always been exhibited by mankind since the dawn of time. Even the Bible has ample evidence of this.
One hardly needs to be a Bible scholar or student of prophecy to see these signs in our world today. Just pick up your daily newspaper or turn on the television news! The evidence is all around us.
The only reason why the evidence is all around us is that we have access to so much information because of the internet and 24 hour news stations. If something happens in the world today it is flashed around the world within minutes.
