The current system is grossly inefficient. Hundreds of billions of dollars are wasted every year, and billions more go uncollected because of tax evasion, or because of mistakes and oversights due to complex and ever-changing tax laws. There are also billions of dollars of tax revenue lost because of black market or illegal cash transactions that are un-auditable and uncollectible. Not to mention the millions of tax dollars evaded annually by illegal aliens living in this country. Additionally, many complain that the tax load is not borne fairly among all citizens.
Tax rates vary greatly from household to household.
People who can afford tax lawyers compensate for high taxes by finding loopholes, creating a constant battle of regulation and revisions. Other government officials say the IRS's problems now jeopardize the funding of the government. Many Americans say it's time for a change. There are many in government who support a fairer, more productive system of taxation as well. Senator Richard Lugar from Indiana claims that his national sales tax proposal would do away with the IRS altogether.
