Define "equal treatment". No--I'm not joking, but let me explain.
One of the divides is "equal opportunity" vs "equal outcome". Both are forms of "equal treatment".The first is where everyone gets an equal chance. But some people will fail. Why? Everyone has different gifts and talents and some have more in some areas. And some people will fail big time. So some people get hurt. And some get rich.
But a lot of folks see "income inequity" (which is in itself a loaded term) and want equal outcome. That's been tried. And failed. Again, people are not equal in their abilities or efforts--so some folks wonder why they should work any harder (the old Russian joke: "We pretend to work and they pretend to pay us"). Some decide "why work". And again, people get hurt. And again it doesn't work as planned. A group of people takes over. As noted socialist Orwell noted about these systems "All animals are equal, but some animals are more equal than others". And if equal outcome is the goal, why am I not a PSU football player?
For me, I prefer the former system--but with a reasonable safety net for the less fortunate. But, we're human. Which ever one you choose will be flawed.
