In 1845 the richest 4 percent of population of new york city owned how much of the city's individual wealth

I believe the answer is: 80%

At that time, there was no regulation regarding minimum wages, which make business owners able to obtain more profit by reducing the salary of the workers. The number has came down ever since but the gap is still particularly high now (10% of the richest owned more than 40%)

where is the subject? hahahaha
