If you don’t need EASA, don’t do it! And those 1500 hours is total time so it doesn’t matter where you get them from. If you apply at a Part 135 airline you can get a flying job at a regional even with 500 hours. Flight training is much cheaper and there are less regulations in the US. Starting salaries at the start are on par with airlines such as Wizz Air and other low cost carriers but once you get some more experience and fly for a major they pay much better than any top airline in Europe.
