if you make $80K a year, you probably have insurance through your employer. Let's take the Frost family instead, but we'll give them a raise to $50K a year for convenience's sake.
OK our family of 4 at $50K pays about $6700 in taxes (not including payroll taxes) which leaves them a monthly income of $3607 a month. Before FICA mind you, and if you are self employed that doubles your FICA costs. about 15% actually, so now you're down to $3065 a month before you pay local and state taxes.
Now the 'tax break' offered, is that a deduction or a credit?
A credit is a dollar-for-dollar reduction of the taxes you owe. A $100 credit means you pay $100 less in taxes. A deduction reduces the taxes you owe by a percent of every dollar you're allowed to deduct.
You calculate the worth of your deduction by multiplying your marginal (or top) tax rate by the amount of the deduction. If you're in the 25 percent tax bracket, a $100 deduction means you'll pay $25 less in taxes (0.25 times $100). http://money.cnn.com/magazines/moneymag/money101/lesson18/index.htmso out of the $3065 a month our fictional family would (on the average) pay $6772 a year for a family plan
http://www.ahrq.gov/news/press/pr2002/insprepr.htm if they had no preexisting conditions and could get insurance.
so now our fictional family's income is $2500 a month. to cover housing, food, gas and everything else. the Average cost of housing and utilities (assuming a 3 bedroom apartment) is $1056, the average car payment is $378 and we'll assume they have two, the average food cost is $874 (per the USDA)the average credit card payment is $200 our little family is already paying $380 more than their income before they buy any gasoline.
How is this gonna work again? where will they find the cash to pay for insurance? You know it's gonna be the first thing they have to let go.
