If you lived in the period of 1850, probably half of you wouldn't make it to their 25-30ies.
As of the age of 10-12 you would be working in factories, 12-14 hours a day, 6-7 days a week in poor safety and filthy conditions, low pay, abuse and bosses as bullies. You didn't get a regular meal, hardly get a break, were payed per week or fired per day. The money you earned was taken by your boss, family or father...
who probably spent it on alcohol.
It was in fact modern slavery. No surprise that people started to organise themselves.
