Today's Psalm is Psalm 49, another Psalm from the sons of Korah.
The Psalmist exhorts everybody to listen to his wisdom, "both low and high, rich and poor together". There is no special status for anyone with respect to the ability to know God, or in the fate we suffer if we neglect to do so.
He continues with a disclosure about redemption, it cannot be bought, at any price:
Those who trust in their wealth
And boast in the multitude of their riches,
None of them can by any means redeem his brother,
Nor give to God a ransom for him
For the redemption of their souls is costly,
And it shall cease forever
That he should continue to live eternally,
And not see the Pit.
He notes two things about redemption: that no one can buy it, it is greater than the riches of any man, and when life runs out, the time to obtain it has ceased forever (more clear in the NASB translation perhaps)
The Psalmist goes on to note that all men die, the wise man and the foolish together; while we all think our houses will last forever, in the end, we are just like all the animals of the earth in that we all perish. However, he notes that God will redeem him from the power of the grave, and receive him. In the end he notes:
A man who is in honor, yet does not understand, Is like the beasts that perish.
What is there to understand? That life is all about loving God with all your heart, soul, mind, and strength, the first commandment. (Mark 12:30)
