In the past, firms contracted workers for 60 hour weeks, gave them no paid holiday and had little on no health and safety or sick pay etc etc. Does that mean those workers were 'tough' or they were better off because of it? No, they died much younger because if it, and they didn't choose it, but had to accept the hours and conditions because that was what was needed to earn a barely living wage.
Do people have an easier life today than that? Most people do - most people can work and earn a living wage in less hours and have paid holiday and other protections. In one sense life today might be easier, but there might be other aspects which are harder. Are we 'softer' or less hard working or less worthy than people in the past? We might live an easier life due to mid cons and rules and regulations, but it doesn't make those workers less worthy.
Today, some people work very long hours. Some have shorter contracted hours but work much longer due to expectation or other reasons, others work very long hours because their job pays poorly and they need to work harder to earn a living wage - rather like the workers of previous times who simply had to do the long hours to earn a barely living wage. Others earn what they need in jobs which require fewer hours and where there isn't an expectation to work lots of extra hours. They are working less - are they luckier - only in relation to throw who have no choice but to work excessive hours in order to live. They aren't luckier or softer than those who opt for jobs with longer hours or who choose to work lots of hours beyond their contracts.
Long hours only really make sense if you have no alternative, need to work them to live or if you thoroughly enjoy your work, or if it is a means to another end, or if you working longer has no impact on anyone such as family. Otherwise, you could say that working longer hours is a daft idea - not tough, or brave or hardworking, but either a sign of being a martyr, pushover, obsessed with money, a sign of having no outside life or not caring about the impact it has on family.
Work is one part of life. As others said, we should work to live, not the other way round. If we can enjoy our work and find it rewarding,mall to the good, but work-life balance is very important for well-being, health and family, and those things seem more important than an idea that long hours is a sign cof strength and short hours of being flaky and weak.
