The idea that there can be a labour shortage in an industry that does not require specialized skills, at a time in history where capital has more power than ever is a total joke.
If you're talking about the last decade, maybe. In the current month/year? No, because the government is currently paying people to stay at home at rates competitive to employment[1]. With that taken into account labor's power is arguably stronger than ever.
[1] The median US hourly wage is $15.35 (https://www.statista.com/statistics/185335/median-hourly-ear...). With the $300/week subsidy from the federal government and 50% of hourly wage from unemployment, that works out to $15.18 for staying at home.
