Things have certainly changed at the pro clubs now as well as at any teams that have proper coaches.
The problem in this country is that you don't need any formal coaching qualifications to be able to coach kids at school or saturday/sunday league. That means a lot of kids get bad coaching early on in their development.
I remember when I was a kid, the difference it made to me when I played first district and then county football, both of which had a proper qualified coach. Whereas for years at school and with sunday league football our 'coaches' were absolute wallies.
The reason I went and did my UEFA badge was because I thought I might want to get involved in helping with the coaching of my own sons as they started to play sunday league football and I didn't want to be one of those absolute wallies.
The problem with football is that so many people love it and so many people want to get involved with it, but most of those people actually haven't really got a clue about the game. So many of our kids get taught bad habits and aren't given the right chance to improve by people who actually mean well.
I think Iceland have a policy where anyone coaching kids (from age 4 up) to play football have to have a coaching qualification. So all PE teachers and all kids saturday/sunday football team coaches there have a UEFA badge. Iceland's FA subsidised these coaching qualifications (no doubt using their income to do this instead of using that money to pay for their 'executives' to fly first class, stay in grand hotels and have long boozy lunches in Michelin starred restaurants as is the priority of 'other' FA's) Iceland (population 340 odd thousand) now have more qualified coaches than England. It is no coincidence that they became the smallest country by population to qualify for a World Cup.
