Why? A bit more info would be useful.
Our EMV rollout in the US was awful, the software running on card terminals is abysmally slow to authenticate transactions (taking upwards of 15 seconds in some cases), while traditional magnetic strips took maybe 2 or 3 to authorize. This is fixable, and multiple vendors in the chain have been providing fixes that drop the authentication+authorization time back down to the 3 second window, but it's going to take a while for it to get rolled out now that it's almost a full year after the big switch.
With chip you have to put it in the machine and leave it there until the transaction is finished, including signing. Only then can you take it out, exactly at the moment when you should be grabbing your bags.
It's much slower.
First my cheques are free, and the only time I really use them is when somebody needs by account info on file.
Second I have a chip card and I hate it.
Third, you're right. US telecom blows.
Fourth I hate to break it to you but talent really does flock to the US from europe and elsewhere and many of our greatest scientists and entrepreneurs are from abroad. Hell, Elon Musk is South African. That is the result of an extremely innovation friendly investment community, and the best higher education (UK is a distant second), in the world.
