If the foundations are destroyed, what can the righteous do?”

Psalm 11:3

"When the foundations are being destroyed,

    what can the righteous do?”

I saw a BRICK SUPPORT column with a mortar crack patched with caulking, I thought surely this could not fix the cracked mortar or the weakened support. I thought about the worker who may have done this, probably young, summer help, with little experience.
I then thought about foundations as mentioned in the Bible.

“If you destroy the foundations, if you take good people off from their hope in God,...., you ruin them, and break their hearts indeed.."(MHC)
