why would anyone work hard to become an attorney
Do you really think becoming an attorney is harder than, say, cleaning toilets 40h/week? I finished my master‘s degree in physics recently. Has it been stressful? Sure. But I could mostly choose my own rhythm to work, had a healthy balance of exercise and leisure, and had coffee breaks all the time. I know a carpenter and some farm workers, and I would have chosen uni over their work at any time. And chances are, once I get a „real job“ it will still be less hard than working on a field.
Wages are mostly a measure for how replaceable you are, not for how hard the work is.
Fortunately, snail speed doesn‘t scale linearly with size, as the relativ slowing down of oxygen diffusion into the cells would shut down metabolic processes in the snail and lead to its asphyxiation.
