Where was Marco Polo from & what was his family's primary source of income?

Marco Polo (September 15, 1254, Venice, Italy; or Curzola, Venetian Dalmatia - now Korčula, Croatia — January 8, 1324, Venice) was a Venetian trader and explorer who, together with his father Niccolò and his uncle Maffeo, was one of the first Westerners to travel the Silk Road to China (which he called Cathay) and visited the Great Khan of the Mongol Empire, Kublai Khan (grandson of Genghis Khan).

This means that he was probably from Venice or Curzola(now in Croatia). Neither have been corroborated by historical evidence.

The main source of his family's income was a golden tablet (or paiza in Chinese, gerege in Mongolian) a foot long and three inches wide and inscribed with the words (Left Fig.): "By the strength of the eternal Heaven, holy be the Khan's name. Let him that pays him not reverence be killed." This tablet was given to his family by Kublai Khan

I'm the primary breadwinner for my family and I do like being able to have the bills paid on time, living in a nice place, and having money for entertainment and other spending, however, stress is a big factor. When you have to juggle a career AND a household it gets to be too much at times. I wonder if primary income earning men are pulling double duty as far as home and career? Do they come come and do laundry, make dinner, help the kids with homework, feed and play with the baby, get things ready for tomorrow and try and be the sizzling sexpot in the bedroom on a regular basis? It's hard to stand proud when you carry so much for the majority of the time...
