The worst of all the multitude
Did something for the common good.
This was the state's craft, that maintain'd
The whole, of which each part complain'd:
This, as in musick harmony,
Made jarrings in the main agree;
Parties directly opposite,
Assist each oth'r, as 'twere for spight;
And temp'rance with sobriety
Serve drunkenness and gluttony.
The root of evil, avarice,
That damn'd ill-natured baneful vice,
Was slave to prodigality,
That noble sin; whilst luxury
Employ'd a million of the poor,
And odious pride a million more:
Envy itself and vanity
Were ministers of industry;
Their darling folly, fickleness
In diet, furniture, and dress,
That strange ridic'lous vice, was made
The very wheel that turn'd the trade.
Their laws and cloaths were equally
Objects of mutability;
For what was well done for a time,
In half a year became a crime;
Yet whilst they altered thus their laws,
Still finding and correcting flaws,
They mended by inconstancy
Faults which no prudence could foresee.
Thus vice nursed ingenuity,
Which join'd with time and industry,
Had carry'd life's conveniencies,
It's real pleasures, comforts, ease,
To such a height, the very poor
Lived better than the rich before;
And nothing could be added more.
