Yes. It makes them less likely to get off their a@&$- & learn, develop, improve & be self-sufficient.
Unfortunately, corruption at varying levels in their society, helps not one bit.
So what's to do?
STOP the aid! MAKE them do things correctly. This will depend on their level of education. But continuosly giving handouts is not the way, unless it's directed properly. And this may need overseers to do that.
Case in point. Australia looked after TPNG. All worked extremely well, & flowed efficiently for decades'. The country DEMANDED self-governmentship. They got their wish in 1975.
Since then, the country's been going to 'hell in a hand basket' extremely rapidly, mostly due to corruption, which cannot be controlled.
PNG could've been possibly one of THE wealthiest countries' in the world, with its' natural beauty & associated activities eg diving, hiking, allowing much tourism, the mining boom there & forestry industry.
They lost that opportunity because they THOUGHT they could do WITHOUT external governance. WRONG! Bigtime.
The country has been spiralling out of control for years. They're on the brink of bankruptcy. It needn't have come to this.
They made the mess they're in. They'll have to sort it out for THEMSELVES! After all, that's what self-government is all about!
Good luck with THAT!
