Dear shack

Kings are usually born in palaces
Presidents dwell in high places
Rulers oft discuss lofty ideas
The rich strike great deals
They all shut their doors to keep nuances outside,
for within is not everybody's abode
but for the select

But you dear shack
you welcome all, producing the great
Only when they become great do they despise you dear shack
Yet you are ever ready to welcome them back when they do.
