taxes should be based off of income and bills, not just straight how much you make.
for instance, if I made $100k a year ($8,333/mo), but had a $2500 mortgage payment, $1k car payments and $1500 in bills every month, that would put me at $5k/mo. After taxes, that leaves my $8,333 to $5,833 (assuming 30%), so I have $833 left over each month for savings, going out, luxuries, etc.
Now, if I made $100k a year but had no car payment, $600/mo bills (everyone has bills) and maybe a $1200/mo mortgage that leaves me with over $4,000/mo!
Sure, the first guy thats his own fault, but what if that guy has a family of 5 and his cost of living is higher because of where he lives due to his job. While guy 2 is single and works at home from his Internet company.
IMO, guy #2 should have to pay a little more tax that guy #1. For example, guy #1 pays 25% in tax while guy #2 pays 35% in tax which gives guy #1 an extra $416.75 in his pocket every month.
