whose work caused public uproar that contributed to the passage of these laws a) Upton Sinclair b) Jacob riis c) Jane addams d) w. e.b. du bois​

not really sure i needed the points. sorry

most people such as me i dont have one but if   i did i would mostly likely quit my job if the economy was down cylcling that means less money if you go to a bigger job that is prospering you can earn more wage and still be able to feed yourself or why you work all people want more money then they have guarteed most people like me would switch jobs for a better one with higher wage

less available tax revenue

this basically means that when they get money from taxes wirth having a lower gdp they get less then what others have with a higher gdp

im not sure but i have a question for you?
