Paradoxes of our civilized life

We invest large sums of money in shelters for stray dogs but we do not care of abandoned children who starving,
We have the largest amount of information ever, yet we are ignorant,
We are smart, too intelligent to become wiser,
Those who have something to say do not have time to do it, and those who have nothing to say have enough time,
We fight windmills for selfish idea of ours, but we will not move a finger for our neighbor found in trouble,
We all always run to find answer to life, but we forget to live meanwhile.
