Left cold by riches and nobility = feel cold in living riches and nobility?

Context:

Absurdly he courts care and melancholy
And raves like any madman in his folly;
For though endowed with handsome looks is he,
His heart is lawless and refractory.
Too dense by far to understand his duty,
Too stubborn to apply himself to study,
Foolhardy in his eccentricity,
He’s deaf to all reproach and obloquy.

Left cold by riches and nobility,
Unfit to bear the stings of poverty,
He wastes his time and his ability,
Failing his country and his family.
First in this world for uselessness is he,
Second to none in his deficiency.
Young fops and lordlings all, be warned by me:
Don’t imitate this youth’s perversity!
