I decided to default on my credit card bill because then it can save me for rent and food. is it good decision?

i only made minimum payments and now the balance is almost 15,000 dollars. i get fired from job because of being late to work excessively (by 5 to 10 minutes only). So now i decided to default on credit card bill. Moreover, the bank whose credit card i use already got big bailout from government in 2008 and also other card-holders can pay my bill because my bill will be sent to them in form of higher interest rates and higher fees. My credit get bad but i don't care. For good credit, i cannot stay hungry and homeless
