First off all I'm presuming innocence. Secondly I'm not sure how things work in America but generally here in the UK a business or person will have a gross turnover / income. From this various business expenses / allowances will be deducted and the remainder will be taxed. After this happens your left with company profit / net income. Hence if it's a business expense like legal fees or an allowance like for example PPE ( personal protective equipment ) it is not tax deductible.
Assuming things are similar in the US and every citizen enjoys the same benefits that would lead me to think that if the average tax payer set up their own business or was self employed they could enjoy at least a 1 time business allowance of $130,000 if they suffer the misfortune of stresses they would like to go away. This would obviously have to be facilitated by a legal eagle of their choice.
This raises another question. Does the average American voter expect the same rights as Trump?
