Would you make a purchase under the table to avoid what you feel is an unfair tax?

When the government wants to tax second-hand clothing it just gripes my gore that their hands are so deep into our pockets, especially pockets that can’t afford it. There must be some way of controlling the outpour into the government coffers. Sorry, it’s not so much of an outpour as a sucking vacuum. Is buying under the table something you would consider? BTW, I am not referring specifically to used clothing. I mean some purchases in general.
