在家冇嘢做，上網check咗一啲關於美國debt ceiling嘅資料，當中找到以下一些有趣資料。
細心D看，我想中學生都會想到美國息口會升得快唔快，可以或可能升到去邊。
美國啲debt outstanding，由1992十年間從USD 4 trillion 左右升左4倍，至2012年嘅16 trillion，利息付出由292 billion，升左唔到25%至396 billion。
如果你有financial calculator 的話，用average inflation for past 10 years=3.5%計一計，你就知道美國佬有幾叻，佢地食左免費午餐幾耐，同時又想再食幾耐！
如果佢地唔繼續食的話，我睇唔到佢地有能力找數囉。買左UST(US Treasury)嗰啲國家，就不斷地努力賺錢俾佢地免費食！
那誰買得最多D美味的齋，中國是也。唉！係唔係中國人永遠都要活在美國佬腳下。以前是過去舊金山做cheap labour，依家都沒有改變。
所以，我哋要生性D，唔好日日家嘈屋閉，做多D有用有建設性的正能量東西，早日可以成為真正的龍的傳人。
人民幣快D可以做到各國的reserve currency就好lah！中國領導人加油！中國人民（香港人在內）加油！
