支持认为小幅就业损失换取大幅加薪是值得的
就业小幅下降，换来在职工资上涨约 25%？虽然数据集里每一行都是活生生的人，但总体来看这算是一次巨大的成功吧？

Small decrease in employment in exchange for ~25% higher wages for those employed? Did I get that right? Obviously every single row in the dataset is a unique human, but overall sounds like a big success?
亲历亲历案例：最低工资正加速快餐业自动化和去门店化
这仍然是就业的净损失。我确信未来会通过进一步自动化来减少人手。我家附近新开了一家麦当劳，没有堂食座位，只能通过 App 或得来速下单。店主告诉我两个原因：一是当地无家可归者问题不断，二是想尽量减少员工——没有堂食区要打扫、没有柜台要值守，需要的员工就少了。我敢肯定这就是加州未来的方向。

It's still a net loss of jobs. I'm certain the future will involve increasing automation to further reduce headcount. A McDonald's recently opened near me with no seating, and orders can only be placed through the app or at the drive thru. I spoke with the owner who mentioned two main reasons for this setup: first, ongoing issues with the local homeless population and second, a desire to minimize staffing. Fewer employees are needed when there's no dining area to clean or counter to staff. I’m pretty sure this is the direction things are headed in California.
补充道德立场：付不起体面工资的企业本就不该存在
如果一家企业付不起维持生计的工资，它就不该存在。就这么简单。想象一下用同样的方法分析'要求企业给奴隶付工资'的影响，得出某些奴隶制企业会倒闭的结论——谁在乎呢！我们不想要一个只能靠这种商业模式运转的公司。奴隶式劳动不应补贴人为压低的价格和虚高的高管薪酬。

If a business can't provide a living wage, it shouldn't exist. It's really that simple. Imagine doing this analysis on the effects of requiring a business to pay it's slaves, and coming to the conclusion that some slave-based businesses would have to close, since their business model was so skewed, it could only function with slave labor... Who cares! We don't want a world with companies that can only work with those kinds of business models! Slave labor shouldn't subsidize artificially low priced products and artificially inflated executive salaries... the end.
质疑经济学视角：最低工资把低边际价值劳动者挤出就业市场
最低工资讨论中常被忽视的几点：1) 由于市场力量，工资本来就会达到或接近最低标准，且无需付出官僚、执法、税收和扭曲的代价；2) 最低工资会让边际价值低于该标准的人无法就业——如果某人边际价值是 15 美元/小时，你不会花 20 美元雇他。这对那些愿意以 x 美元/小时工作、却生活在法定最低工资高于 x 的州的人来说是灾难性的：他们从低薪就业变成了失业。

Some things often overlooked in minimum wage discussions: - Wages often go over or close to the minimum anyway, due to market forces, and do so without costly bureaucracy/enforcement/taxation/distortion - Minimum wages make everyone whose marginal value is less than the minimum wage unemployable (since you would choose not to hire someone for $20/hour if their marginal value is $15). This is disastrous for someone who'd love to work at $x/hour, but who lives in a state which legislates a minimum wage > $x/hour, since they go from being employed at a low wage to unemployed.
