JEFFERSON CITY - As state leaders prepare to develop a budget with less money than last year, about 100 protesters gathered on the front steps of the Capitol Building Thursday denouncing cuts to social services and proposed changes to the state's tax structure.

The rally, held by Mexico, Mo.-based Grass Roots Organizing, included speeches on issues affecting the poor in the state, including access to health care and higher education, as well as proposals in the General Assembly that would scrap the state's income and corporate taxes and replace them with what supporters call the "fair tax."

To offset lost income tax revenue, the fair tax would increase the states sales tax rate, as well increasing the number of items and services that would be subject to sales tax.  Services such as health care and tuition, which are currently not subject to sales tax, could be taxed as part of some fair tax proposals.

Show-Me Institute founder and former investment banker Rex Sinquefield was public enemy number one for the protesters. Sinquefield has bankrolled efforts to institute a fair tax in the state.

On the Capitol steps, demonstrators introduced "Rex", their representation of Sinquefield, who was a young man in a top hat and a large green cloak with dollar signs emblazoned upon the front.

Demonstrators carried signs baring the St. Louis businessman's name and face on a "wanted" poster with the moniker "Sin Man" above his image. After speeches at the Capitol concluded, the group walked a few blocks away and continued protesting in front of the office of Kent Gaines, a lobbyist for Sinquefield.    

Robin Acree, the director of Grass Roots Organizing, called the fair tax plan a "radical scheme."  

"This is a risky gamble," Acree said. "This is not a casino. We are not going to be your social guinea pigs."

In an address to the crowd, Brenda Procter, a co-founder of Grass Roots Organizing, discussed ideas for the state to raise revenue. Her suggestions included updating the state's income tax structure, instituting a "streamlined" sales tax that collects revenue from Internet transactions, and eliminating tax exemptions for out-of-state corporations with operations in Missouri.

"We have many solutions to budget problems besides cutting services for Missourians," Procter said.

As the protest took place outside the Capitol, the Senate debated a bill proposed by Sen. Chuck Purgason, R-Caulfield, that would institute the fair tax. The bill was held over for a final vote until after the legislature's week long spring break. If passed, the decision to enact the plan would be subject to approval by Missouri voters.     

Calls to spokeswoman for Sinquefield and to Gaines' office were not returned Thursday afternoon.
