I doubt it ever been different. In the old days the friendships were there out of need as well. Today we no longer need another and if that's the case we are more selfish. Not that being selfish is a bad thing. Too many always sacrifice everything to help somene out. In the end that is what eats you. All energy, time and money invested in someone taking you for granted.

I wish you a few friends, it's enough since you have to invest in them.
