Electricity powered homes and factories. how did electricity change americans' lives?

Electricity is what powers our everyday lives! We use it to power lightbulbs so we can see at night, and it also powers streetlights so we can drive in the dark. Heck, without electricity we wouldn't have cars in the first place! The very computer you asked this question on wouldn't exist either!

Electricity made a whole new type of transportation able to be created! It also made instant communication with one another possible! The world as you know it today would not be possible without electricity, it does much more than I mentioned in this answer too!

they became hereditary because there weren't many jobs for people in lower classes

i do believe the answer is false.
