Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Should the US have a federal minimum wage, or should it be left to the states?

 The question of whether the United States should have a federal minimum wage, or whether it should be left to the states to set their own minimum wages, is a matter of ongoing debate. Proponents of a federal minimum wage argue that it is necessary to ensure that all workers in the country are paid a fair and living wage, regardless of where they live. They argue that a federal minimum wage helps to reduce poverty and income inequality, and that it helps to stimulate the economy by increasing the purchasing power of low-wage workers. Opponents of a federal minimum wage argue that it can be harmful to small businesses and can lead to job losses, as companies may not be able to afford to pay their workers the higher wage. They argue that it is better to leave the decision of what the minimum wage should be to the states, so that it can be tailored to the specific economic conditions of each state. Ultimately, the decision of whether to have a federal minimum wage or to leave the matter to the states is a policy choice that depends on the specific circumstances and goals of the country.
