Insulin is released from the beta cells in your pancreas in response to rising glucose in your bloodstream. After you eat a meal, any carbohydrates youâve eaten are broken down into glucose and passed into the bloodstream. The pancreas detects this rise in blood glucose and starts to secrete insulin.
A regressive tax is a tax imposed in such a manner that the tax rate decreases as the amount subject to taxation increases. Regressive describes a distribution effect on income or expenditure, referring to the way the rate progresses from high to low, so that the average tax rate exceeds the marginal tax rate.
Other taxes like sales tax are often called regressive taxes in order to make them compare poorly with income tax in terms of their fairness. The rationale is that individuals or families at the low end of the income spectrum spend a higher proportion of their income than those at the high end.
